str_getcsv
If you want to keep the original capitalization when replacing some text (e.g. for highlighting the search-string in the the search result), you can use this code I wrote:
<?php
// http://devboard.viathinksoft.de/viewtopic.php?f=34&t=771
// Bugfix-Release #3 (June, 22th 2009)
function ext_str_ireplace($findme, $replacewith, $subject)
{
// Replaces $findme in $subject with $replacewith
// Ignores the case and do keep the original capitalization by using $1 in $replacewith
// Required: PHP 5
$rest = $subject;
$result = '';
while (stripos($rest, $findme) !== false) {
$pos = stripos($rest, $findme);
// Remove the wanted string from $rest and append it to $result
$result .= substr($rest, 0, $pos);
$rest = substr($rest, $pos, strlen($rest)-$pos);
// Remove the wanted string from $rest and place it correctly into $result
$result .= str_replace('$1', substr($rest, 0, strlen($findme)), $replacewith);
$rest = substr($rest, strlen($findme), strlen($rest)-strlen($findme));
}
// After the last match, append the rest
$result .= $rest;
return $result;
}
?>
str_ireplace
(PHP 5)
str_ireplace — Bir alt dizgenin bütün örneklerini yenisiyle değiştirirken harf büyüklüklerini dikkate almaz
Açıklama
Harf büyüklüğüne duyarsız olarak konu dizgesi içindeki eski dizgelerinin her birini yeni dizgesiyle değiştirerek elde edilen dizi veya dizgeyi döndürür. Kaprisli yer değiştirme kurallarına ihtiyacınız olmayacaksa (düzenli ifadeler gibi) preg_replace() işlevini i değiştiricisi ile kullanmak yerine daima bu işlevi kullanın.
Değiştirgeler
- eski
-
Bilginize: eski dizisindeki her yer değiştirme önceki yer değiştirme sonucunun üzerine uygulanır.
- yeni
-
- konu
-
Eğer konu bir dizi ise, arama ve değiştirme her eleman için ayrı ayrı yapılır ve dönen değer de bir dizi olur.
- sayı
-
Eğer belirtilirse, yer değiştirilen dizgelerin sayısı bu değiştirgede döndürülür.
Eğer eski ve yeni birer dizi ise str_replace() her diziden birer değer alıp bunları kullanarak konu dizgesinde arama ve yer değiştirme yapar. Eğer yeni dizisi eski dizisinden daha az değere sahipse eksik kalan yeni dizgelerin yerine boş dizgeler konur. Eğer eski bir dizi ve yeni bir dizge ise her eski dizgesinin yerine bu yeni dizgesi konur. Zıddı anlamlı değildir.
Dönen Değerler
Yer değiştirmeler yapılmış dizge veya diziyi döndürür.

Here's a different approach to search result keyword highlighting that will match all keyword sub strings in a case insensitive manner and preserve case in the returned text. This solution first grabs all matches within $haystack in a case insensitive manner, and the secondly loops through each of those matched sub strings and applies a case sensitive replace in $haystack. This way each unique (in terms of case) instance of $needle is operated on individually allowing a case sensitive replace to be done in order to preserve the original case of each unique instance of $needle.
<?php
function highlightStr($haystack, $needle, $highlightColorValue) {
// return $haystack if there is no highlight color or strings given, nothing to do.
if (strlen($highlightColorValue) < 1 || strlen($haystack) < 1 || strlen($needle) < 1) {
return $haystack;
}
preg_match_all("/$needle+/i", $haystack, $matches);
if (is_array($matches[0]) && count($matches[0]) >= 1) {
foreach ($matches[0] as $match) {
$haystack = str_replace($match, '<span style="background-color:'.$highlightColorValue.';">'.$match.'</span>', $haystack);
}
}
return $haystack;
}
?>

This function will highlight search terms (Key Words in Context).
The difference between this one and the ones below is that it will preserve the original case of the search term as well. So, if you search for "american" but in the original string it is "American" it will retain the capital "A" as well as the correct case for the rest of the string.
<?php
function kwic($str1,$str2) {
$kwicLen = strlen($str1);
$kwicArray = array();
$pos = 0;
$count = 0;
while($pos !== FALSE) {
$pos = stripos($str2,$str1,$pos);
if($pos !== FALSE) {
$kwicArray[$count]['kwic'] = substr($str2,$pos,$kwicLen);
$kwicArray[$count++]['pos'] = $pos;
$pos++;
}
}
for($I=count($kwicArray)-1;$I>=0;$I--) {
$kwic = '<span class="kwic">'.$kwicArray[$I]['kwic'].'</span>';
$str2 = substr_replace($str2,$kwic,$kwicArray[$I]['pos'],$kwicLen);
}
return($str2);
}
?>

Example for str_ireplace(). It will print "RePlaCeMe" in red color, but after this, it would be written in lower case because of the string $search.
<?php
$search = 'replaceme';
$replace = '<font color="#FF0000">'.$search.'</font>';
$text = 'Please RePlaCeMe, OK?';
echo str_ireplace($search, $replace, $text);
?>
Example for ext_str_ireplace(). It will print "RePlaCeMe" in red color, and will not change the capitalization:
<?php
$search = 'replaceme';
$replace = '<font color="#FF0000">$1</font>';
$text = 'Please RePlaCeMe, OK?';
echo ext_str_ireplace($search, $replace, $text);
?>

I modified a script from notes on the eregi_replace() function page. This is a highlight script that worked good for me.
$text - is the text to search
$words - are the words to highlight (search text)
$the_place - is so that you can tell your users what "area" was searched.
<?php
function highlight_this($text, $words, $the_place) {
$words = trim($words);
$wordsArray = explode(' ', $words);
foreach($wordsArray as $word) {
if(strlen(trim($word)) != 0)
$text = str_ireplace($word, "<span class=\"highlight\">".strtoupper($word)."</span>", $text, $count);
}
//added to show how many keywords were found
echo "<br><div class=\"emphasis\">A search for <strong>" . $words. "</strong> found <strong>" . $count . "</strong> matches within the " . $the_place. ".</div><br>";
//end script modification
return $text;
}
?>

Here are some minor tweaks to-n00b-at-battleofthebits-dot-org's excellent function.
1) The token was set to an ASCII value 1 (which could be changed as was previously noted)
2) The $c++ was not needed
3) The while statement is not necessary for the final replacement
4) Note that this does not allow use of arrays for search and replace terms. That could be implemented using loops.
<?php
if(!function_exists('str_ireplace')){
function str_ireplace($search,$replace,$subject){
$token = chr(1);
$haystack = strtolower($subject);
$needle = strtolower($search);
while (($pos=strpos($haystack,$needle))!==FALSE){
$subject = substr_replace($subject,$token,$pos,strlen($search));
$haystack = substr_replace($haystack,$token,$pos,strlen($search));
}
$subject = str_replace($token,$replace,$subject);
return $subject;
}
}
?>

Note that character case is being defined by your server's locale setting, which effects strings containing non-ASCII characters.
See strtolower() - http://www.php.net/strtolower and comments - internally str_ireplace converts $search and $replace to lowercase to find matches.

here's a neat little function I whipped up to do HTML color coding of SQL strings.
<?php
/**
* Output the HTML debugging string in color coded glory for a sql query
* This is very nice for being able to see many SQL queries
* @access public
* @return void. prints HTML color coded string of the input $query.
* @param string $query The SQL query to be executed.
* @author Daevid Vincent [daevid@LockdownNetworks.com]
* @version 1.0
* @date 04/05/05
* @todo highlight SQL functions.
*/
function SQL_DEBUG( $query )
{
if( $query == '' ) return 0;
global $SQL_INT;
if( !isset($SQL_INT) ) $SQL_INT = 0;
//[dv] this has to come first or you will have goofy results later.
$query = preg_replace("/['\"]([^'\"]*)['\"]/i", "'<FONT COLOR='#FF6600'>$1</FONT>'", $query, -1);
$query = str_ireplace(

If you want to do string highlighting, for example highlighting search terms, try str_highlight().

This functionality is now implemented in the PEAR package PHP_Compat.
