str_split
(PHP 5)
str_split — Convert a string to an array
Description
array str_split
( string
$string
[, int $split_length = 1
] )Converts a string to an array.
Parameters
-
string -
The input string.
-
split_length -
Maximum length of the chunk.
Return Values
If the optional split_length parameter is
specified, the returned array will be broken down into chunks with each
being split_length in length, otherwise each chunk
will be one character in length.
FALSE is returned if split_length is less than 1.
If the split_length length exceeds the length of
string, the entire string is returned as the first
(and only) array element.
Examples
Example #1 Example uses of str_split()
<?php
$str = "Hello Friend";
$arr1 = str_split($str);
$arr2 = str_split($str, 3);
print_r($arr1);
print_r($arr2);
?>
The above example will output:
Array
(
[0] => H
[1] => e
[2] => l
[3] => l
[4] => o
[5] =>
[6] => F
[7] => r
[8] => i
[9] => e
[10] => n
[11] => d
)
Array
(
[0] => Hel
[1] => lo
[2] => Fri
[3] => end
)

The manual don't says what is returned when you parse a different type of variable.
This is the example:
<?php
$str1 = "Long"; // More than 1 char
$str2 = "x"; // Only 1 char
$str3 = ""; // Empty String
$str4 = 34; // Integer
$str5 = 3.4; // Float
$str6 = true; // Bool
$str7 = null; // Null
$spl1 = str_split($str1);
$spl2 = str_split($str2);
$spl3 = str_split($str3);
$spl4 = str_split($str4);
$spl5 = str_split($str5);
$spl6 = str_split($str6);
$spl7 = str_split($str7);
echo count($spl1); // 4
echo count($spl2); // 1
echo count($spl3); // 1
echo count($spl4); // 2
echo count($spl5); // 3
echo count($spl6); // 1
echo count($spl7); // 1
print_r($spl1);
print_r($spl2);
print_r($spl3);
print_r($spl4);
print_r($spl5);
print_r($spl6);
print_r($spl7);

Response to "Richard Ayotte 18-Jan-2008 09:27":
Slight tweak to prevent the need to call another preg_replace, there were also some bugs in this that I'm surprised didn't get noticed (causing duplicate replaces between the preg_replace calls) :)
Please feel free to optimize further. I'm not the best with lookahead/behinds yet. I also removed the :upper/lower: and it seemed to speed things up too.
<?php
$test = 'CustomerIDWithSomeOtherJETWords';
preg_replace('/(?!^)[A-Z]{2,}(?=[A-Z][a-z])|[A-Z][a-z]/', ' $0', $test));
?>
Shaves off a little time anyway. :)

Version of str_split by rlpvandenberg at hotmail dot com is god-damn inefficient and when $i+$j > strlen($text) [last part of string] throws a lot of notice errors. This should work better:
if(! function_exists('str_split'))
{
function str_split($text, $split = 1)
{
$array = array();
for ($i = 0; $i < strlen($text);)
{
$array[] = substr($text, $i, $split);
$i += $split;
}
return $array;
}
}

I think that the last post by carlosreche at yahoo dot com is too complicated.
It's much easier if you do it like this:
<?php
if (!function_exists("str_split")) {
function str_split($str,$length = 1) {
if ($length < 1) return false;
$strlen = strlen($str);
$ret = array();
for ($i = 0; $i < $strlen; $i += $length) {
$ret[] = substr($str,$i,$length);
}
return $ret;
}
}
?>
I hope it helps for those with PHP <5

I needed a function that could split a string from the end with any left over chunk being at the beginning of the array (the beginning of the string).
<?php
function str_rsplit($str, $sz)
{
// splits a string "starting" at the end, so any left over (small chunk) is at the beginning of the array.
if ( !$sz ) { return false; }
if ( $sz > 0 ) { return str_split($str,$sz); } // normal split
$l = strlen($str);
$sz = min(-$sz,$l);
$mod = $l % $sz;
if ( !$mod ) { return str_split($str,$sz); } // even/max-length split
// split
return array_merge(array(substr($str,0,$mod)), str_split(substr($str,$mod),$sz));
}
$str = 'aAbBcCdDeEfFg';
str_split($str,5); // return: {'aAbBc','CdDeE','fFg'}
str_rsplit($str,5); // return: {'aAbBc','CdDeE','fFg'}
str_rsplit($str,-5); // return: {'aAb','BcCdD','eEfFg'}

the fastast way (that fits my needs) to replace str_split() in php 4 i found is this:
<?php
if(!function_exists('str_split')) {
function str_split($string, $split_length = 1) {
$array = explode("\r\n", chunk_split($string, $split_length));
array_pop($array);
return $array;
}
}
?>
i also tested the provided functions in the comments..
(the differences are 0.001 to 0.00001 sec)

A good use of str_split is reverse translating an amino acid sequence.
<?php
/* reverse translate an aa sequence using its dna counterpart */
function reverseTranslate($aaSeq,$ntSeq){
$nt=str_split($ntSeq,3);
$aa=str_split($aaSeq,1);
$gapChar=array('*','-');
$numAa=count($aa);
$ntIndex=0;
$newNtSeq="";
for($i=0;$i<$numAa;$i++){
// if the aa is a gap, then just put on a gap character
if(in_array($aa[$i],$gapChar)){
$newNtSeq.='---';
}
else{
$newNtSeq.=$nt[$ntIndex];
$ntIndex++;
}
}
return $newNtSeq;
}

A good way to use this method to convert CamelCase text into nice text would be-
<?php
/**
Returns a formatted string based on camel case.
e.g. "CamelCase" -> "Camel Case".
*/
function FormatCamelCase( $string ) {
$output = "";
foreach( str_split( $string ) as $char ) {
strtoupper( $char ) == $char and $output and $output .= " ";
$output .= $char;
}
return $output;
}

I was looking for a function that would split a string into an array like str_split() and found Razor's function above. Just though that I would simplify the code a little.
<?php
function str_split_php4($text, $split = 1){
//place each character of the string into and array
$array = array();
for($i=0; $i < strlen($text); $i++){
$key = NULL;
for ($j = 0; $j < $split; $j++){
$key .= $text[$i];
}
array_push($array, $key);
}
return $array;
}
?>
Both mine and worksRazor's work well, I just prefer to use less code. I could have written one myself, but I was just being lazy.

If you use PHP 4 and don't need the split_length parameter, here's the shortest replacement:

A little one-liner that came in handy. I thought i'd share for those who want to split a string into two parts by the given offset.
<?php
/**
* Split a string into two parts at offset.
*
* @param string $string
* @param integer $offset
* @return mixed array and bool(false) if offset is out of scope
*/
function str_osplit($string, $offset){
return isset($string[$offset]) ? array(substr($string, 0, $offset), substr($string, $offset)) : false;
}
$str = "Split a string into two parts at offset";
var_dump(str_osplit($str, 12));
/**
* Output:
array(2) {
[0]=>
string(12) "Split a stri"
[1]=>
string(27) "ng into two parts at offset"
}
*/
?>

For those it may concern:
We encountered trubble when trying to str_split a UTF-8 encoded string, containing such Swedish letters as å, å and ö.
It seems that this function splits according to byte-length and not character length. So if the letter "Å" takes 2 bytes, then str_split() will only return the first bite of the character "Å".
We ain't 100% sure that this is the case but this was anyhow the result we got. So we used the multi-byte functions instead.

The documentation fails to mention what happens when the string length does not divide evenly with the chunk size. Not sure if the same behavior for all versions of PHP so I offer the following code to determine this for your installation. On mine [version 5.2.17], the last chunk is an array the length of the remaining chars.
<?php
$da_string = "When number of chars does't divide evenly";
$len = strlen($da_string);
$chunk_size = 8;
echo "<p> Length of <span style='font-family:monospace'>$da_string</span>: $len</p>\n";
echo "<p> Chunck size: $chunk_size</p>\n";
$parts = str_split($da_string, $chunk_size);
$html = "<table border='5' cellpadding='3' cellspacing='4'>\n";
foreach ($parts as $idx=>$part)
{
$html .= "<tr>\n";
$html .= "<td style='font-family:monospace'>$part</td>";
$chars = str_split($part);
foreach ($chars as $char)
{
if ($char === ' ')
{
$html .= "<td> </td>";
}
else
{
$html .= "<td>$char</td>";
}
}
$html .= "</tr>\n";
}
$html .= "</table>\n";
echo $html;

Regarding ricordatis comment on preg_match_all('/./u',...) instead of preg_split('//u',...):
You'll have to use the pattern '/./us' with preg_match_all to get exactly the same behaviour w.r.t. newlines. Don't know if this is still faster, though. Oh, and the expected result is in $array[0].

The previous suggestion is almost correct (and will only working for strlen=1. The working PHP4 function is:
<code>
function str_split($text, $split = 1){
//place each character of the string into and array
$array = array();
for ($i=0; $i < strlen($text); $i++){
$key = "";
for ($j = 0; $j < $split; $j++){
$key .= $text[$i+$j];
}
$i = $i + $j - 1;
array_push($array, $key);
}
return $array;
}

this function can perform a reverse str_split. I write it for PHP4 but you can rename It for other versions..
if ( !function_exists('str_split') ) {
function str_split($string,$split_length=1){
$sign = (($split_length<0)?-1:1);
$strlen = strlen($string);
$split_length = abs($split_length);
if ( ($split_length==0) || ($strlen==0) ){
$result = false;
//$result[] = "";
}
elseif ($split_length >= $strlen){
$result[] = $string;
}
else {
$length = $split_length;
for ($i=0; $i<$strlen; $i++){
$i=(($sign<0)?$i+$length:$i);
$result[] = substr($string,$sign*$i,$length);
$i--;
$i=(($sign<0)?$i:$i+$length);
if ( ($i+$split_length) > ($strlen) ){
$length = $strlen-($i+1);
}
else {
$length = $split_length;
}
}
}
return $result;

The very handy str_split() was introduced in PHP 5, but a lot of us are still forced to use PHP 4 at our host servers. And I am sure a lot of beginners have looked or are looking for a function to accomplish what str_split() does.
Taking advantge of the fact that strings are 'arrays' I wrote this tiny but useful e-mail cloaker in PHP, which guarantees functionality even if JavaScript is disabled in the client's browser. Watch how I make up for the lack of str_split() in PHP 4.3.10.
<?php
// cloackEmail() accepts a string, the email address to be cloaked
function cloakEmail($email) {
// We create a new array called $arChars, which will contain the individula characters making up the email address. The array is blank for now.
$arChars = array();
// We extract each character from the email 'exploiting' the fact that strings behave like an array: watch the '$email[$i]' bit, and beging to fill up the blank array $arChars
for ($i = 0; $i < strlen($email); $i++) { $arChars[] = $email[$i]; }
// Now we work on the $arChars array: extract each character in the array and print out it's ASCII value prefixed with '&#' to convert it into an HTML entity
foreach ($arChars as $char) { print '&#'.ord($char); }
// The result is an email address in HTML entities which, I hope most email address harvesters can't read.
}
print cloakEmail('someone@nokikon.com');
?>
###### THE CODE ABOVE WITHOUT COMMENTS ######
<?php
function cloakEmail($email) {
$arChars = array();
for ($i = 0; $i < strlen($email); $i++) { $arChars[] = $email[$i]; }
foreach ($arChars as $char) { print '&#'.ord($char); }
}
print cloakEmail('someone@nokikon.com');
?>
In creating this little utility, I demonstrated how the lack of str_split() can be made up in PHP < 5. If you got how it was accomplished, you could write a function to do exactly what str_split() does in PHP 5 and even name it 'str_split()'. :)

An easy way to split long texts in columns/pages with entire last words
<?php
$text = "This is a very very long text ... the end"; // ie 7000 cars.
$max_car = 1500; // content length of each page/col
// we first split the text in equal parts
$pages = str_split($text, $max_car);
// we now get something like
// $pages 1 = "This is a .... very long te"
// $pages 2 = "xt but first/last words are cutted"
// we now find each last whitespace of each col/page
foreach ($pages as $content) {
$content = $report.$content; //add the reported cars of previous page (ie "te" to get "text" on page2)
$last_space = strrpos($content," ");
$page = substr($content,0,$last_space);
$report = str_replace($page,'',$content); // reported cars
// we now get
// $pages 1 = "This is a .... very long"
// $pages 2 = "text and first/last words are OK"
echo $page;

dacmeaux at gmail dot com's version might work well for a $split value of 1, but above that, it just repeats the one character per array field and based on the $split value. The following does it right:
<?php

// place each character of the string into and array
$array = array();
for ( $i=0; $i < strlen( $text ); ){
$key = NULL;
for ( $j = 0; $j < $split; $j++, $i++ ) {
$key .= $text[$i];
}
array_push( $array, $key );

return $array;

If you are looking for a way to split multibyte strings then this may come in handy:
<?php
$text = "süpérbrôsé";
function mb_str_split($str, $length = 1) {
if ($length < 1) return FALSE;
$result = array();
for ($i = 0; $i < mb_strlen($str); $i += $length) {
$result[] = mb_substr($str, $i, $length);
}
return $result;
}
$solo = mb_str_split($text);
$quintet = mb_str_split($text, 5);
print_r($solo);
print_r($quintet);
?>
Spits out:
Array
(
[0] => s
[1] => ü
[2] => p
[3] => é
[4] => r
[5] => b
[6] => r
[7] => ô
[8] => s
[9] => é
)
Array
(
[0] => süpér
[1] => brôsé
)

Note to function by carlosreche at yahoo dot com.
The while:
<?php
...
while ($str_length--) {
$splitted[$i] = $string[$i++];
}
...
?>
.. result in index starting at 1.
Ie: str_split("ABC") gives
Array
(
[1] => A
[2] => B
[3] => C
)
While php5's str_split("ABC") gives
Array
(
[0] => A
[1] => B
[2] => C
)
And his str_split("ABC",2) gives index starting at 0.
Change to this (or something similar):
<?php
...
while ($str_length--) {
$splitted[$i] = $string[$i];
$i++;
}
...
?>
.... or use heavyraptor's function. A bit more sclick,..

[Editor's Note: Or just: php.net/wordwrap]
This is a little function to split a string into shorter strings with max lenght $n in such way, that it don't split words (it search for spaces), it's usefull for articles or sth.
Result is put in $ttab variable, and function result is number of "pages".
<?php
function divide_text($text, $n, &$ttab) {
$ttab = array();
$l = strlen($text); // text length
$cb = 0; //copy begin from..
$p = 0; // parts
if ($l <= $n) {
$ttab[0] = $text;
return 1;
} else {
$ctrl = 1;
while(((($p-1) * $n) < $l) && ($ctrl < 100)) {
$crtl++; // control variable, to protect from infinite loops
$tmp = substr($text, $cb, $n);
// we're looking for last space in substring
$lastpos = strrpos($tmp," ");
if ( (is_bool($lastbool) && !$lastpos) || ( $l - $cb <= $n)) {
$ttab[$p] = $tmp;
} else {
$tmpgood = trim(substr($tmp, 0,$lastpos)); // if they were another spaces at the end..
$ttab[$p] = $tmpgood;
$cb += $lastpos + 1 ;
}; // if
$p++;
}; //for
return $p;
}; // if
} // divide text
?>

//fast & short version od str_split PHP3, 4x
function string_split($str, $nr){
return split("-l-", chunk_split($str, $nr, '-l-'));
}
//example :
print_r(string_split('123412341234', 4));
