str_getcsv
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;
}
}
?>
Description
str_ireplace() retourne une chaîne de caractères ou un tableau dont toutes les occurrences de search dans subject (en ignorant la casse), ont été remplacées par la valeur de replace . Si vous n'avez pas besoin de règles de recherche complexes, il est recommandé d'utiliser cette fonction qui est plus rapide que eregi_replace() ou preg_replace(), exploitant l'option i.
Si subject est un tableau, le remplacement est effectué sur chacun des éléments du sujet subject , et la valeur retournée est un aussi un tableau.
Si search et replace sont des tableaux, alors str_replace() prendra une valeur de chaque tableau, et l'utilisera pour faire le remplacement dans subject . Si replace a moins de valeurs que search , alors une chaîne vide sera utilisée pour effectuer les remplacements. Si search est un tableau et que replace est une chaîne, alors la chaîne de remplacement sera utilisée pour chaque élément de search .
Note: Chaque remplacement avec le tableau search est effectué sur le résultat du dernier remplacement.
Exemple #1 Exemple avec str_ireplace()
<?php
$bodytag = str_ireplace("%body%", "black", "<body text=%BODY%>");
?>
Cette fonction est compatible avec les données binaires.
Note: Depuis PHP 5.0, le nombre de valeurs de needle trouvées et remplacées sera retourné dans le paramètre count passé par référence. Avant PHP 5.0.0, ce paramètre n'est pas disponible.
Voir aussi str_replace(), preg_replace() et strtr().

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);
}
}
?>

str_ireplace for php below version 5. :)
if(!function_exists('str_ireplace')) {
function str_ireplace($search,$replace,$subject) {
$search = preg_quote($search, "/");
return preg_replace("/".$search."/i", $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.

here's a neat little function I whipped up to do HTML color coding of SQL strings.
<?php

* @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]

* @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);

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