note 35387 modified in function.strrpos by vincent

I should have looked here first, but instead I wrote my own version of strrpos that supports searching for entire strings, rather than individual characters. This is a recursive function. I have not tested to see if it is more or less efficient than the others on the page. I hope this helps someone! //Find last occurance of needle in haystack function str_rpos($haystack, $needle, $start = 0){ $tempPos = strpos($haystack, $needle, $start); if($tempPos === false){ if($start == 0){ //Needle not in string at all return false; }else{ //No more occurances found return $start - strlen($needle); } }else{ //Find the next occurance return str_rpos($haystack, $needle, $tempPos + strlen($needle)); } } --was-- I should have looked here first, but instead I wrote my own version of strrpos that supports searching for entire strings, rather than individual characters.
