There's no way to do that with str_replace(). You'll need to use regular expressions with ereg_replace() or something like it.I'm not sure, but I think this might do what you want:

$firstvar = "aaa&SomeMoreStuff";$newvar = ereg_replace('^.*\&','FOUND',$firstvar);echo $newvar;

Search Google for "regex tutorial" or "regular expressions" to find more about regular expressions, which is the first argument of this function.

Otherwise you would need to use strpos to find the position of the &, and then use substr to get everything after it. You can add the FOUND text onto the beginning yourself.

$pos = strpos($str, "&");if ($pos !== false){  $str = "FOUND" . substr($str, $pos);}
