note 96308 added to function.substr-replace

My problem was that substr_replace() always added $replacement, so i wrote my own function. This function only adds $replacement, if substr() took action. The parameter $length is optional - like substr()'s. Or I was too stupid using $start and $length... <?php function substr_replace_provided($string,$replacement,$start,$length=NULL) { $tmp=substr($string,$start,$length); if($string!==$tmp) { $string = $tmp.$replacement; } return $string; } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 87.189.252.208 ---- Manual Page -- http://www.php.net/manual/en/function.substr-replace.php Edit -- https://master.php.net/note/edit/96308 Del: integrated -- https://master.php.net/note/delete/96308/integrated Del: useless -- https://master.php.net/note/delete/96308/useless Del: bad code -- https://master.php.net/note/delete/96308/bad+code Del: spam -- https://master.php.net/note/delete/96308/spam Del: non-english -- https://master.php.net/note/delete/96308/non-english Del: in docs -- https://master.php.net/note/delete/96308/in+docs Del: other reasons-- https://master.php.net/note/delete/96308 Reject -- https://master.php.net/note/reject/96308 Search -- https://master.php.net/manage/user-notes.php
