note 104251 added to function.trim

On my application I had several users submit what to me appeared as "empty strings", whereas in fact they were submitting the &shy; character. Trim, by default, does not strip this character (Though arguably it should). The following code strips this character from your input: <?php // As the &shy; character is invisible we'll simply use the ASCII numeric representation, and decode via chr(): $string = trim($string, chr(173)); // If you wish to strip all occurences this will work: $string = str_replace(chr(173), "", $string); ?> Gerard ---- Server IP: 213.249.64.162 Probable Submitter: 83.87.181.228 ---- Manual Page -- http://www.php.net/manual/en/function.trim.php Edit -- https://master.php.net/note/edit/104251 Del: integrated -- https://master.php.net/note/delete/104251/integrated Del: useless -- https://master.php.net/note/delete/104251/useless Del: bad code -- https://master.php.net/note/delete/104251/bad+code Del: spam -- https://master.php.net/note/delete/104251/spam Del: non-english -- https://master.php.net/note/delete/104251/non-english Del: in docs -- https://master.php.net/note/delete/104251/in+docs Del: other reasons-- https://master.php.net/note/delete/104251 Reject -- https://master.php.net/note/reject/104251 Search -- https://master.php.net/manage/user-notes.php
