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... CentOS 6.5 PHP-FPM 5.4.35
var_dump(strpos('mrwagon',626));//1 tadaaam!
