Description:
------------
When using strpos inside a foreach and the needle is the key of the array being looped over one get strange return values. Not all key and not all length of the haystack produces this result, and not all needle/haystacks produce the same faulty return value

Reproduce code:
---------------
$maps = array('919400' => 'foo');
foreach ($maps as $orgnr => $foo)
	var_dump(strpos('ou=000000,ou=000000,ou=000000,ou=0000000000,ou=organization,dc=chalmers,dc=se', $orgnr));


Expected result:
----------------
bool(false)

Actual result:
--------------
int(64)

"If needle is not a string, it is converted to an integer and applied as the ordinal value of a character."
In your case needle is int(919400). 
chr(919400) returns "h", so you got what you was looking for: "h" is 65-th symbol in your string.
