note 82307 added to function.rtrim

I'm sure there's a better way to strip strings from the end of strings. /** * Strip a string from the end of a string * * @param string $str the input string * @param string $remove OPTIONAL string to remove * * @return string the modified string */ function rstrtrim($str, $remove=null) { $str = (string)$str; $remove = (string)$remove; if(empty($remove)) { return rtrim($str); } $len = strlen($remove); $offset = strlen($str)-$len; while($offset > 0 && $offset == strpos($str, $remove, $offset)) { $str = substr($str, 0, $offset); $offset = strlen($str)-$len; } return rtrim($str); } //End of function rstrtrim($str, $remove=null) echo rstrtrim('Hello World!!!', '!') .'<br />'; //"Hello World" echo rstrtrim('Hello World!!!', '!!') .'<br />'; //"Hello World!" echo rstrtrim('Hello World!!!', '!!!') .'<br />'; //"Hello World" echo rstrtrim('Hello World!!!', '!!!!').'<br />'; //"Hello World!!!" ---- Server IP: 64.71.164.2 Probable Submitter: 66.27.49.42 ---- Manual Page -- http://www.php.net/manual/en/function.rtrim.php Edit -- https://master.php.net/note/edit/82307 Del: integrated -- https://master.php.net/note/delete/82307/integrated Del: useless -- https://master.php.net/note/delete/82307/useless Del: bad code -- https://master.php.net/note/delete/82307/bad+code Del: spam -- https://master.php.net/note/delete/82307/spam Del: non-english -- https://master.php.net/note/delete/82307/non-english Del: in docs -- https://master.php.net/note/delete/82307/in+docs Del: other reasons-- https://master.php.net/note/delete/82307 Reject -- https://master.php.net/note/reject/82307 Search -- https://master.php.net/manage/user-notes.php
