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
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 $replacewith
// Required: PHP 5
return substr($subject, 0, stripos($subject, $findme)).
str_replace('$1', substr($subject, stripos($subject, $findme), strlen($findme)), $replacewith).
substr($subject, stripos($subject, $findme)+strlen($findme));
}
?>
Example for using:
<?php
$search = 'replaceme';
$text = 'Please RePlaCeMe, OK?';
// Will print "RePlaCeMe" with red color, but after this it would be "replaceme", not "RePlaCeMe"
$replace = '<font color="#FF0000">'.$search.'</font>';
echo str_ireplace($search, $replace, $text);
// Will print "RePlaCeMe" with red color
$replace = '<font color="#FF0000">$1</font>';
echo ext_str_ireplace($search, $replace, $text);
?>
Descrizione
Questa funzione restituisce una stringa od una matrice con tutte le occorrenze di search in subject (non distinguendo tra maiuscole e minuscole) sostituite con il valore replace Se non occorrono particolari regole di sostituzione si dovrebbe utilizzare questa funzione anziché eregi_replace() o preg_replace() con il parametro i.
Se il parametro subject è una matrice, allora la ricerca e la sostituzione viene eseguita su ogni elemento di subject , ed il valore restituito è pure quello una matrice.
Se search e replace sono matrici, allora str_ireplace() prende i valori da ciascuna matrice e li utilizza per fare la ricerca e la sostituzione in subject . Se replace ha meno valori di search , allora si utilizza una stringa vuota per sostituire i valori mancanti. Se search è una matrice e replace è una stringa; allora questa stringa viene utilizzata per sostituire ogni valore di search .
Example #1 Esempio di uso di str_ireplace()
<?php
$bodytag = str_ireplace("%body%", "black", "<body text=%BODY%>");
?>
Questa funzione è sicura con i dati binari.
Nota: Dal PHP 5.0.0 il numero dei testi trovati e sostituiti sarà restituito in count che deve essere passato per riferimento. Prima del PHP 5.0.0 questo parametro non è disponibile.
Vedere anche: str_replace(), ereg_replace(), preg_replace() e strtr().

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'm really sorry, there is a big bug in my previous mb_str_ireplace function: here's the correct one:
<?php
/**
* Case insensitive multi-byte safe str_ireplace
* @param string $search
* @param string $replace
* @param string $subject
* @param int $count
* @param string $encoding
* @return string
*/
function mb_str_ireplace($search, $replace, $subject, $count = null, $encoding = u8) {
$l1 = mb_strlen($search, $encoding);
$l2 = mb_strlen($replace, $encoding);
$rc = 0;
$offset = 0;
while(ok($p = mb_stripos($subject, $search, $offset, $encoding)) && (is_null($count) || $rc <= $count)) {
if (ok($p))
$subject = mb_substr($subject, 0, $p, $encoding) . $replace . mb_substr($subject, $p + $l1, mb_strlen($subject, $encoding), $encoding);
$offset = $p + $l2;
$rc++;
}
return $subject;
}
?>
To make it mb_str_replace - change stripos to strpos. I'm sorry for previous bug, well, this one is tested.
I wonder should I publish my growing mb_ functions library like WORKING mb_wordwrap WITHOUT regexes (faster)... E-mail me.

It's obvious str_ireplace() won't be multi-byte safe. Function mb_str_ireplace() is missing in php, so here's mine:
<?php
/**
* Case insensitive multi-byte safe str_replace
* @param string $search
* @param string $replace
* @param string $subject
* @param int $count
* @param string $encoding
* @return string
*/
function mb_str_ireplace($search, $replace, $subject, $count = null, $encoding = 'utf-8') {
$l1 = mb_strlen($search, $encoding);
$rc = 0;
$offset = 0;
while (ok($p = mb_stripos($subject, $search, $offset, $encoding)) && (is_null($rc) || $rc <= $count)) {
if (ok($p)) $subject = mb_substr($subject, $offset, $p, $encoding) . $replace . mb_substr($subject, $p + $l1, mb_strlen($subject, $encoding), $encoding);
$offset = $p + $l1;
$rc++;
}
return $subject;
}
?>
It works exactly like original str_ireplace() and defaults to 'utf-8' encoding. Replace with null if you like. Well, it's surely slower than built-in functions, however it's one of the fastest ways to do the trick.

My apologies. I'm a PHP newbie and the count function on my script below didn't work right if you have more than one "keyword". I searched and spent a long time to get this to work right, so wanted to share it.
This is very easy to use by doing the following.
$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);
$the_count = 0;
$wordsArray = explode(' ', $words);
foreach($wordsArray as $word) {
if(strlen(trim($word)) != 0)
//exclude these words from being replaced
$exclude_list = array("word1", "word2", "word3");
// Check if it's excluded
if ( in_array( strtolower($word), $exclude_list ) ) {
} else {
$text = str_ireplace($word, "<span class=\"highlight\">".strtoupper($word)."</span>", $text, $count);
$the_count = $count + $the_count;
}
}
//added to show how many keywords were found
echo "<br><div class=\"emphasis\">A search for <strong>" . $words. "</strong> found <strong>" . $the_count . "</strong> matches within the " . $the_place. ".</div><br>";
return $text;
}
//example of how to use
$text_to_highlight = highlight_this($text_to_highlight, $search_text, "Place you searched");
?>

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;
}
}
?>

Dreamhost hasn't upgraded to PHP 5.0 -- I came up with my own alternative, trying to make it run as much like str_ireplace() as possible. Adjust the switch-a-roo token if you think it may conflict with your needle in teh haystack.
## HOMEBREW str_ireplace() FOR PRE-PHP 5.0
if (!function_exists('str_ireplace') {
function str_ireplace($search,$replace,$subject) {
$token = '^[[term^]';
$haystack = strtolower($subject);
$needle = strtolower($search);
while (($pos=strpos($haystack,$needle))!==FALSE) {
$c++;
$subject = substr_replace($subject,$token,$pos,strlen($search));
$haystack = substr_replace($haystack,$token,$pos,strlen($search));
}
while (($pos=strpos($subject,$token))!==FALSE) {
$subject = substr_replace($subject,$replace,$pos,strlen($token));
}
return $subject;
}
}

There appears to be a "bug" with this function in at least version 5.2.1.
If you attempt to use the function while replacing special characters, such as new lines, it will cause your entire scripts to fail. It resulted in my browser (Firefox 2) trying to download the file instead of parsing it.
Here is example code which will cause problems:
<?php
$sometext = "this is some text\n";
$sometext .= "that has a new line in it";
echo break_lines($sometext);
function break_lines ($text)
{
return str_ireplace("\n", "<br/>", $text);
}
?>
However, if you simply get rid of the "i" and use the normal str_replace, the page will load just fine.
I have also tried the same code on 5.2.3 and this version does NOT have the same problem, so it does appear to be an issue that was resolved with the newest builds of php.
I don't think it was a result of my personal environment, but I am running Debian-Sarge, Apache 2 and PHP 5.2.1/5.2.3.

Yet another one str_ireplace ireplacement, this one will take arrays as $search and $replace
<?php
function make_pattern(&$pat, $key) {
$pat = '/'.preg_quote($pat, '/').'/i';
}
if(!function_exists('str_ireplace')){
function str_ireplace($search, $replace, $subject){
if(is_array($search)){
array_walk($search, 'make_pattern');
}
else{
$search = '/'.preg_quote($search, '/').'/i';
}
return preg_replace($search, $replace, $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.
