note 82788 added to function.trim

I've noticed that many needs to remove multiple lines in the end of a string, so I made this function. Pretty easy, actually. It removes all unnecessary newlines (or something else, if $char is set) <?php function remove_unnecessary ($str, $char = "\n") { while (true) { if (substr ($str, -(strlen($char))) == $char) { $str = substr ($str, 0, -(strlen($char))); } else { break; } } return $str; } $Str = "Hello\nHello\n\n\n\n\n\n\n\n\n"; // Outputs: Hello\nHello echo remove_unnecessary ($Str); ?> ---- Server IP: 62.73.196.231 Probable Submitter: 85.164.224.129 ---- Manual Page -- http://www.php.net/manual/en/function.trim.php Edit -- https://master.php.net/note/edit/82788 Del: integrated -- https://master.php.net/note/delete/82788/integrated Del: useless -- https://master.php.net/note/delete/82788/useless Del: bad code -- https://master.php.net/note/delete/82788/bad+code Del: spam -- https://master.php.net/note/delete/82788/spam Del: non-english -- https://master.php.net/note/delete/82788/non-english Del: in docs -- https://master.php.net/note/delete/82788/in+docs Del: other reasons-- https://master.php.net/note/delete/82788 Reject -- https://master.php.net/note/reject/82788 Search -- https://master.php.net/manage/user-notes.php
