ucwords

(PHP 4, PHP 5, PHP 7)

ucwords将字符串中每个单词的首字母转换为大写

说明

ucwords ( string $str [, string $delimiters = " \t\r\n\f\v" ] ) : string

str 中每个单词的首字符(如果首字符是字母)转换为大写字母,并返回这个字符串。

这里单词的定义是紧跟在 delimiters 参数(默认:空格符、制表符、换行符、回车符、水平线以及竖线)之后的子字符串。

参数

str

输入字符串。

delimiters

可选的 delimiters,包含了单词分割字符。

返回值

返回转换后的字符串。

更新日志

版本 说明
5.4.32, 5.5.16 增加了 delimiters 参数。

范例

Example #1 ucwords() 范例

<?php
$foo 
'hello world!';
$foo ucwords($foo);             // Hello World!

$bar 'HELLO WORLD!';
$bar ucwords($bar);             // HELLO WORLD!
$bar ucwords(strtolower($bar)); // Hello World!
?>

Example #2 ucwords() 自定义 delimiters 的例子

<?php
$foo 
'hello|world!';
$bar ucwords($foo);             // Hello|world!

$baz ucwords($foo"|");        // Hello|World!
?>

My quick and dirty ucname (Upper Case Name) function.

<?php
//FUNCTION

function ucname($string) {
   
$string =ucwords(strtolower($string));

    foreach (array(
'-', '\'') as $delimiter) {
      if (
strpos($string, $delimiter)!==false) {
       
$string =implode($delimiter, array_map('ucfirst', explode($delimiter, $string)));
      }
    }
    return
$string;
}
?>
<?php
//TEST

$names =array(
 
'JEAN-LUC PICARD',
 
'MILES O\'BRIEN',
 
'WILLIAM RIKER',
 
'geordi la forge',
 
'bEvErly CRuSHeR'
);
foreach (
$names as $name) { print ucname("{$name}\n"); }

//PRINTS:
/*
Jean-Luc Picard
Miles O'Brien
William Riker
Geordi La Forge
Beverly Crusher
*/
?>

You can add more delimiters in the for-each loop array if you want to handle more characters.

Para formatar nomes em pt-br:

<?php

   
function titleCase($string, $delimiters = array(" ", "-", ".", "'", "O'", "Mc"), $exceptions = array("de", "da", "dos", "das", "do", "I", "II", "III", "IV", "V", "VI"))
    {
       
/*
         * Exceptions in lower case are words you don't want converted
         * Exceptions all in upper case are any words you don't want converted to title case
         *   but should be converted to upper case, e.g.:
         *   king henry viii or king henry Viii should be King Henry VIII
         */
       
$string = mb_convert_case($string, MB_CASE_TITLE, "UTF-8");
        foreach (
$delimiters as $dlnr => $delimiter) {
           
$words = explode($delimiter, $string);
           
$newwords = array();
            foreach (
$words as $wordnr => $word) {
                if (
in_array(mb_strtoupper($word, "UTF-8"), $exceptions)) {
                   
// check exceptions list for any words that should be in upper case
                   
$word = mb_strtoupper($word, "UTF-8");
                } elseif (
in_array(mb_strtolower($word, "UTF-8"), $exceptions)) {
                   
// check exceptions list for any words that should be in upper case
                   
$word = mb_strtolower($word, "UTF-8");
                } elseif (!
in_array($word, $exceptions)) {
                   
// convert to uppercase (non-utf8 only)
                   
$word = ucfirst($word);
                }
               
array_push($newwords, $word);
            }
           
$string = join($delimiter, $newwords);
       }
//foreach
      
return $string;
    }

?>

Usage:

<?php
    $s
= 'SÃO JOÃO DOS SANTOS';
   
$v = titleCase($s); // 'São João dos Santos'

UTF-8 Title Case that works for me even with hyphens involved!

$str = 'ĐaaČaa-AAAaaa, BBbb';

$str = mb_convert_case($str, MB_CASE_TITLE, "UTF-8");

echo($str): 'Đaačaa-Aaaaaa, Bbbb'

Some recipes for switching between underscore and camelcase naming:

<?php
// underscored to upper-camelcase
// e.g. "this_method_name" -> "ThisMethodName"
preg_replace('/(?:^|_)(.?)/e',"strtoupper('$1')",$string);

// underscored to lower-camelcase
// e.g. "this_method_name" -> "thisMethodName"
preg_replace('/_(.?)/e',"strtoupper('$1')",$string);

// camelcase (lower or upper) to underscored
// e.g. "thisMethodName" -> "this_method_name"
// e.g. "ThisMethodName" -> "this_method_name"
strtolower(preg_replace('/([^A-Z])([A-Z])/', "$1_$2", $string));
?>

Of course these aren't 100% symmetric.  For example...
  * this_is_a_string -> ThisIsAString -> this_is_astring
  * GetURLForString -> get_urlfor_string -> GetUrlforString

Features:
- multi byte compatible
- handles multiple delimiters

<?php
function ucwords_specific ($string, $delimiters = '', $encoding = NULL)
{
    if (
$encoding === NULL) { $encoding = mb_internal_encoding();}

    if (
is_string($delimiters))
    {
       
$delimiters str_split( str_replace(' ', '', $delimiters));
    }

   
$delimiters_pattern1 = array();
   
$delimiters_replace1 = array();
   
$delimiters_pattern2 = array();
   
$delimiters_replace2 = array();
    foreach (
$delimiters as $delimiter)
    {
       
$uniqid = uniqid();
       
$delimiters_pattern1[]   = '/'. preg_quote($delimiter) .'/';
       
$delimiters_replace1[]   = $delimiter.$uniqid.' ';
       
$delimiters_pattern2[]   = '/'. preg_quote($delimiter.$uniqid.' ') .'/';
       
$delimiters_replace2[]   = $delimiter;
    }

   
// $return_string = mb_strtolower($string, $encoding);

    }

   
$return_string = implode(' ', $words);

   
$return_string = preg_replace($delimiters_pattern2, $delimiters_replace2, $return_string);

    return
$return_string;
}
?>

Params:
1. string: The string being converted
2. delimiters: a string with all wanted delimiters written one after the other e.g. "-'"
3. encoding: Is the character encoding. If it is omitted, the internal character encoding value will be used.

Example Usage:
<?php
mb_internal_encoding
('UTF-8');
$string = "JEAN-PAUL d'artagnan şŠ-òÀ-éÌ hello - world";
echo
ucwords_specific( mb_strtolower($string, 'UTF-8'), "-'");
?>

Output:
Jean-Paul D'Artagnan Şš-Òà-Éì Hello - World

In the function ucsmart() posted by ieure at php dot net on 04-Dec-2005 11:57, I found a similar problem in this function to what he found in igua's.

<?php
function ucsmart($text)
{
   return
preg_replace('/([^a-z]|^)([a-z])/e', '"$1".strtoupper("$2")',
                      
strtolower($text));
}
?>

"igua's code adds a backslash in front of the first single quote for me. This doesn't alter the content in any way other than changing case."

Actually, it did end up changing the content for me (php 5.0.4) in the way that this function escapes a single quotation (apostrophe) in the MIDDLE of a word.

For example:

who's online?

Became:

Who\'s Online?

The fix is simple however, and merely requires fine-tuning the regular expression:

<?php
function ucsmart($text)
{
   return
preg_replace('/([^a-z\']|^)([a-z])/e', '"$1".strtoupper("$2")',
                      
strtolower($text));
}
?>

(note: while previewing this note before adding it, I am noticing php's website is not correctly displaying the change I made as I wrote it. After the first a-z in the expression, the single quotation should be escaped... If it isn't you will get a parse error! And apoligies if my text here is colored as php code; not my fault!)

This will not escape a single quotation mark which occurs in the middle of a word... Though, you may find that might need to add other characters inside the regular expression if you use other special characters inside your words and if you get funky output.

It's a great expression though! Simple, yet very powerful. Kudos!

"ieure at php dot net", your idea is pure poetry!

The function below will standardize the capitalization on people's names and the titles of reports and essays . You may need to adapt the lists in "$all_uppercase" and "$all_lowercase" to suit the data that you are working with.

function my_ucwords($str, $is_name=false) {
   // exceptions to standard case conversion
   if ($is_name) {
       $all_uppercase = '';
       $all_lowercase = 'De La|De Las|Der|Van De|Van Der|Vit De|Von|Or|And';
   } else {
       // addresses, essay titles ... and anything else
       $all_uppercase = 'Po|Rr|Se|Sw|Ne|Nw';
       $all_lowercase = 'A|And|As|By|In|Of|Or|To';
   }
   $prefixes = 'Mc';
   $suffixes = "'S";

   // captialize all first letters
   $str = preg_replace('/\\b(\\w)/e', 'strtoupper("$1")', strtolower(trim($str)));

   if ($all_uppercase) {
       // capitalize acronymns and initialisms e.g. PHP
       $str = preg_replace("/\\b($all_uppercase)\\b/e", 'strtoupper("$1")', $str);
   }
   if ($all_lowercase) {
       // decapitalize short words e.g. and
       if ($is_name) {
           // all occurences will be changed to lowercase
           $str = preg_replace("/\\b($all_lowercase)\\b/e", 'strtolower("$1")', $str);
       } else {
           // first and last word will not be changed to lower case (i.e. titles)
           $str = preg_replace("/(?<=\\W)($all_lowercase)(?=\\W)/e", 'strtolower("$1")', $str);
       }
   }
   if ($prefixes) {
       // capitalize letter after certain name prefixes e.g 'Mc'
       $str = preg_replace("/\\b($prefixes)(\\w)/e", '"$1".strtoupper("$2")', $str);
   }
   if ($suffixes) {
       // decapitalize certain word suffixes e.g. 's
       $str = preg_replace("/(\\w)($suffixes)\\b/e", '"$1".strtolower("$2")', $str);
   }
   return $str;
}

// A name example
print my_ucwords("MARIE-LOU VAN DER PLANCK-ST.JOHN", true);
// Output: Marie-Lou van der Planc-St.John

// A title example
print my_ucwords("to be or not to be");
// Output: "To Be or Not to Be"

Relating to the mb_ucwords() function posted by Anonymous.  In order for this to actually be multi-byte compliant, you would also need to use mb_substr() and mb_strlen() instead of substr and strlen respectively.

Here it is corrected and extended even further to allow multiple word separators and a list of exceptions to correct after title casing. It's a bit tedious and inelegant, but things frequently are when dealing with human languages.

function mb_ucwords($str) {
    $exceptions = array();
    $exceptions['Hp'] = 'HP';
    $exceptions['Ibm'] = 'IBM';
    $exceptions['Gb'] = 'GB';
    $exceptions['Mb'] = 'MB';
    $exceptions['Cd'] = 'CD';
    $exceptions['Dvd'] = 'DVD';
    $exceptions['Usb'] = 'USB';
    $exceptions['Mm'] = 'mm';
    $exceptions['Cm'] = 'cm';
    //    etc.
   
    $separator = array(" ","-","+");
   
    $str = mb_strtolower(trim($str));
    foreach($separator as $s){
        $word = explode($s, $str);

        $return = "";
        foreach ($word as $val){
            $return .= $s . mb_strtoupper($val{0}) . mb_substr($val,1,mb_strlen($val)-1);
        }
        $str = mb_substr($return, 1);
    }

    foreach($exceptions as $find=>$replace){
        if (mb_strpos($return, $find) !== false){
            $return = str_replace($find, $replace, $return);
        }
    }
    return mb_substr($return, 1);

Q1712 at online dot ms

ucwords() only excepts whitespace in front of a word, although some chars like '"' or '(' normally have no space between them and the following word:
<?php
$title
= 'ELVIS "THE KING" PRESLEY - (LET ME BE YOUR) TEDDY BEAR';
echo
ucwords(strtolower($title));
?>
prints: Elvis "the King" Presley - (let Me Be Your) Teddy Bear

To avoid this i use a small function adding and deleting blanks behind these chars, and using ucwords() in between:

<?php
function my_ucwords($string)
  {
   
$noletters='"([/'; //add more if u need to
   
for($i=0; $i<strlen($noletters); $i++)
     
$string = str_replace($noletters[$i], $noletters[$i].' ', $string);
   
$string=ucwords($string);
    for(
$i=0; $i<strlen($noletters); $i++)
     
$string = str_replace($noletters[$i].' ', $noletters[$i], $string);
    return
$string;
  }

$title = 'ELVIS "THE KING" PRESLEY - (LET ME BE YOUR) TEDDY BEAR';
echo
my_ucwords(strtolower($title));
?>

prints: Elvis "The King" Presley - (Let Me Be Your) Teddy Bear

Thanks a lot brother.

I tested it with a few variations. It works perfectly. Its really great and simple usage of the existing functions. It would be glad to all PHP folks and good to PHP if these kind of functions will be in PHP library on upcoming releases.

<?php

$name1
= "mark-yves robert";
$name2 = "mark-yves robert-bryan";

echo
'<br/>Name 1 (mark-yves robert) =>'.
ucwordspecific($name1,'-'); //returns Mark-Yves Robert

echo '<br/>Name 2 (mark-yves robert-bryan)

=>'
.ucwordspecific($name2,'-');
//returns Mark-Yves Robert-Bryan

function ucwordspecific($str,$delimiter){
$delimiter_space = '- ';
return
str_replace($delimiter_space,$delimiter,ucwords

(str_replace($delimiter,$delimiter_space,$str)));
}

?>

A very easy way to convert to title case:

function titleCase($string)
     {
     return ucwords(strtolower($string));
     }

$myString = "SOME TEXT";

echo titleCase($myString);

//will print, "My Text"

Here is a function to capitalize a last name, accounting for hyphens, apostrophes, "Mc" and "Mac":

<?php
function CapitalizeLastName($name) {
   
$name = strtolower($name);
   
$name = join("'", array_map('ucwords', explode("'", $name)));
   
$name = join("-", array_map('ucwords', explode("-", $name)));
   
$name = join("Mac", array_map('ucwords', explode("Mac", $name)));
   
$name = join("Mc", array_map('ucwords', explode("Mc", $name)));
    return
$name;
}
?>

I speed tested it against functions that used preg_replace() with an "e" modifier, preg_replace_callback(), and a character-by-character parsing.  Unexpectedly, this function using join(), array_map() and explode() was fastest.

This seems to be what people want:

function uc_all($string) {
    $temp = preg_split('/(\W)/', $string, -1, PREG_SPLIT_DELIM_CAPTURE );
    foreach ($temp as $key=>$word) {
        $temp[$key] = ucfirst(strtolower($word));
    }
    return join ('', $temp);
}

The code posted above by Joerg Krause only works for a string which ends with one of the delimiters. A possible fix is:

<?php
$text
= "What?No delimiters,shit happens here.this solves all problems.";
preg_match_all("/(\w+[,. ?])+/U", $text, $words);
preg_match("/(\w+)$/", $text, $lastword);
$words[0][] = $lastword;
foreach(
$words[0] as $part) $uwords[] = ucfirst($part);
$text = implode("", $uwords);
echo
$text;
?>

I did the same thing as Catalin, but for French names.

Here's what I'm doing :

For each word (not considering the single-quote as a word boundary character) :
- Put the word in lower case
- If the word is "de", return, else, put the first letter in upper-case
- See if the second character of the word is a single-quote
- Yes ? Put the next char in upper case
- And if the char before the single quote is D, put it back to lower case (-> d)

This complies with the French rules for capitalization in names.

Sample results :
-d'Afoo Bar
-de Foo Bar
-O'Foo Bar
-Foo'bar

<?php
function my_ucwords($s) {
       
$s = preg_replace_callback("/(\b[\w|']+\b)/s", fixcase_callback, $s);
       
        return
$s;        
       
    }
   
    function
fixcase_callback($word) {

       
$word = $word[1];
       
       
$word = strtolower($word);
       
        if(
$word == "de")
            return
$word;
       
       
$word = ucfirst($word);
       
        if(
substr($word,1,1) == "'") {
            if(
substr($word,0,1) == "D") {
               
$word = strtolower($word);
            }
           
$next = substr($word,2,1);
           
$next = strtoupper($next);
           
$word = substr_replace($word, $next, 2, 1);
        }
       
        return
$word;

Based on code sample originally posted by "Anonymous" on 2005-12-14. The /e modifier is no longer supported by preg_replace(). Rewritten to use preg_replace_callback() instead. Tested with PHP 7.3.

The function below will standardize the capitalization on people's names, addresses, and the titles of reports and essays . Adapt the lists in "$all_uppercase" and "$all_lowercase" to suit the data that you are working with.

function ucwords_title($string, $is_name = false) {
    // Exceptions to standard case conversion
    if ($is_name) {
        $all_uppercase = '';
        $all_lowercase = 'De La|De Las|Der|Van De|Van Der|Vit De|Von|Or|And';
    } else {
        // Addresses, essay titles ... and anything else
        $all_uppercase = 'Us|Ca|Mx|Po|Rr|Se|Sw|Ne|Nw';
        $all_lowercase = 'A|And|As|By|In|Of|Or|To';
    }
    $prefixes = 'Mac|Mc';
    $suffixes = "'S";

    // Trim whitespace and convert to lowercase
    $str = strtolower(trim($string));

    // Capitalize all first letters
    $str = preg_replace_callback('/\\b(\\w)/', function ($m) {
        return strtoupper($m[1]);
    }, $str);

    if ($all_uppercase) {
        // Capitalize acronyms and initialisms (e.g. PHP)
        $str = preg_replace_callback('/\\b(' . $all_uppercase . ')\\b/', function ($m) {
            return strtoupper($m[1]);
        }, $str);
    }
    if ($all_lowercase) {
        // Decapitalize short words (e.g. and)
        if ($is_name) {
            // All occurrences will be changed to lowercase
            $str = preg_replace_callback('/\\b(' . $all_lowercase . ')\\b/', function ($m) {
                return strtolower($m[1]);
            }, $str);
        } else {
            // First and last word will not be changed to lower case (i.e. titles)
            $str = preg_replace_callback('/(?<=\\W)(' . $all_lowercase . ')(?=\\W)/', function ($m) {
                return strtolower($m[1]);
            }, $str);
        }
    }
    if ($prefixes) {
        // Capitalize letter after certain name prefixes (e.g 'Mc')
        $str = preg_replace_callback('/\\b(' . $prefixes . ')(\\w)/', function ($m) {
            return $m[1] . strtoupper($m[2]);
        }, $str);
    }
    if ($suffixes) {
        // Decapitalize certain word suffixes (e.g. 's)
        $str = preg_replace_callback('/(\\w)(' . $suffixes . ')\\b/', function ($m) {
            return $m[1] . strtolower($m[2]);
        }, $str);
    }

    return $str;
}

// A name example
print ucwords_title("MARIE-LOU VAN DER PLANCK-ST.JOHN", true);
// Output: Marie-Lou van der Planc-St.John

// A title example
print ucwords_title("to be or not to be");
// Output: "To Be or Not to Be"

for PHP < 5.4.32 with $delimiters

function _ucwords( $str, $delimiters = " \t\r\n\f\v" ) {

    $delims = preg_split( '//u', $delimiters, -1, PREG_SPLIT_NO_EMPTY );

    foreach ( $delims as $delim ) {
       
        if ( false !== strpos( $str, $delim ) ) {

            $str = implode( $delim, array_map( 'ucfirst', explode( $delim, $str ) ) );
        }

A proper Turkish solution;

<?php
function ucfirst_turkish($str) {
   
$tmp = preg_split("//u", $str, 2, PREG_SPLIT_NO_EMPTY);
    return
mb_convert_case(
       
str_replace("i", "İ", $tmp[0]), MB_CASE_TITLE, "UTF-8").
       
$tmp[1];
}

function
ucwords_turkish($str) {
    return
preg_replace("/(\\w+)/ue", "ucfirst_turkish('\\\\1').'$2'", $str);
}

$str = "iyilik güzelLİK şeker ";
echo
ucwords($str) ."\\n";   // Iyilik GüzelLİK şeker
echo ucwords_turkish($str); // İyilik GüzelLİK Şeker
?>

--removed from orginal function--

<?php
function sentenceNormalizer($sentence_split) {
   
$sentence_split = preg_replace(array('/[!]+/','/[?]+/','/[.]+/'),
                                   array(
'!','?','.'),$sentence_split);       
   
   
$textbad = preg_split("/(\!|\.|\?|\n)/", $sentence_split,-1,PREG_SPLIT_DELIM_CAPTURE);
   
$newtext = array();
   
$count = sizeof($textbad);
   
    foreach(
$textbad as $key => $string) {
        if (!empty(
$string)) {
           
$text = trim($string, ' ');
           
$size = strlen($text);
           
            if (
$size > 1){    
               
$newtext[] = ucfirst(strtolower($text));
            }
                elseif (
$size == 1) {

Response to arif:

We do not need that long functions. In order to make ucwords() worked properly in Turkish words that contain speacial characters, we can use the following command in our php codes:

setlocale(LC_ALL, 'tr_TR');

This will set locale to Turkish.

This will correct capitalisation in names taking note of special capitalisation for Mc..., Mac..., and O'... Other special cases, of which I am not aware, can be added easily.

This is just a slight improvement on "deepdene at email dot com"'s name_case function... Thank you for original function.

<?php

function name_case($name) {
    if( !
$name ) return $name;
   
$newname = strtoupper($name[0]);
   
$break = false;
    for(
$i=1; $i<strlen($name); ++$i ) {
     
$subed = substr($name, $i, 1);
      if(
ord($subed) > 64 && ord($subed) < 123 || ord($subed) > 48 && ord($subed) < 58 ) {
        if(
$break ) {
         
$newname .= strtoupper($subed);
        }
        elseif(
$i > 1 && in_array(substr($newname, $i-2, 2), array('Mc', 'O\'')) || $i > 2 && in_array(substr($newname, $i-3, 3), array('Mac')) ) {
         
$newname .= strtoupper($subed);
        }
        else {
         
$newname .= strtolower($subed);
        }
       
$break = false;
      }
      else {
       
// not a letter - a boundary
       
$newname .= $subed;
       
$break = true;
      }
    }  
    return
$newname;

?>

to convert first letters in a firstname like: "jean-pierre" to "Jean-Pierre":

I simply replace the '-' with a vertical tabulation, because the ucwords() function replace the letter just after it.

so, I use the sentence:
$result=str_replace(chr(11),'-',ucwords(strtolower(str_replace('-',chr(11),$firstname))));

A function knowing about name case (i.e. caps on McDonald etc)

function name_case($name)
{
    $newname = strtoupper($name[0]);   
    for ($i=1; $i < strlen($name); $i++)
    {
        $subed = substr($name, $i, 1);    
        if (((ord($subed) > 64) && (ord($subed) < 123)) ||
            ((ord($subed) > 48) && (ord($subed) < 58)))
        {
            $word_check = substr($name, $i - 2, 2);
            if (!strcasecmp($word_check, 'Mc') || !strcasecmp($word_check, "O'"))
            {
                $newname .= strtoupper($subed); 
            }
            else if ($break)
            {
               
                $newname .= strtoupper($subed);
            }
            else      
            {
                $newname .= strtolower($subed);
            }
             $break=0;
        }
        else
        {
            // not a letter - a boundary
             $newname .= $subed;
            $break=1;
        }
