note 115284 added to function.strpos

Be careful when the $haystack or $needle parameter is an integer. If you are not sure of its type, you should convert it into a string. <?php var_dump(strpos(12345,1));//false var_dump(strpos(12345,'1'));//0 var_dump(strpos('12345',1));//false var_dump(strpos('12345','1'));//0 $a = 12345; $b = 1; var_dump(strpos(strval($a),strval($b)));//0 var_dump(strpos((string)$a,(string)$b));//0 ?> ---- Server IP: 64.71.164.2 Probable Submitter: 65.49.68.155 ---- Manual Page -- http://php.net/manual/en/function.strpos.php Edit -- https://master.php.net/note/edit/115284 Del: integrated -- https://master.php.net/note/delete/115284/integrated Del: useless -- https://master.php.net/note/delete/115284/useless Del: bad code -- https://master.php.net/note/delete/115284/bad+code Del: spam -- https://master.php.net/note/delete/115284/spam Del: non-english -- https://master.php.net/note/delete/115284/non-english Del: in docs -- https://master.php.net/note/delete/115284/in+docs Del: other reasons-- https://master.php.net/note/delete/115284 Reject -- https://master.php.net/note/reject/115284 Search -- https://master.php.net/manage/user-notes.php
