After some comments on IRC, here's an alternate version to the above patch. This second approach avoids creating php_memnstri by simply searching through a copy of haystack which is strtolowered against a strtolowered version of needle (no need to copy that part). http://169.229.139.97/test/str_ireplace.diff-2.txt Should be quicker and cleaner at the cost of a small malloc in the estrndup call.

I still don;t see no real use for this function, you can easily do this with eregi_replace() or preg_replace(). Derick

I may be wrong since I haven't profiled this, but my understanding is that str_replace is much faster than doing either of the regex replacements. For that reason alone, there is a use for it. Shane
