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;
}
}
?>
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().

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
/**

* 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(
array (

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