Extend (ohcc at 163 dot com)s comment: 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 // and wait for interesting...
