Bug description: strpos does not autocast integer needles
Description:
------------
When I use a integer variable as needle to the strpos() function, the
needle is not found.
Reproduce code:
---------------
<?
$str_haystack = '12345';
$str_needle = '3';
$int_haystack = 12345;
$int_needle = 3;
$test = strpos($str_haystack, $str_needle);
var_dump($test);
$test = strpos($str_haystack, $int_needle);
var_dump($test);
$test = strpos($int_haystack, $str_needle);
var_dump($test);
$test = strpos($int_haystack, $int_needle);
var_dump($test);
?>
Expected result:
----------------
Due to the fact the strpos() is declared as int strpos ( string haystack,
string needle [, int offset] )
I would expect that using a integer as needle would cause a implicit type
cast to string. This does not seem to be the case, because using an
integer as needle for strpos() will always return false (bool).
Actual result:
--------------
The call to strpos() with the integer needle return false (bool), while
the call to strpos() with string needles return the actual position within
the haystack.
