this is not a bug, see for example var_dump(45 == '45x');
to work-around this, use the third parameter of both functions: $strict=true

because you use it wrong
bool in_array ( mixed $needle , array $haystack [, bool $strict = FALSE ] )
http://php.net/manual/en/language.types.type-juggling.php
________________
[harry@rh:/downloads]$ php test.php
bool(true)
bool(false)
________________
[harry@rh:/downloads]$ cat test.php
<?php
$needle = '45x';
$haystack = ["23", 34, 45, "abc"];
$result = in_array($needle, $haystack);
var_dump($result);
$result = in_array($needle, $haystack, TRUE);
var_dump($result);

Description:
------------
This is the scenario:
- the needle is a string that starts with a numeric content (eg: "45x")
- haystack contains a numeric item that match the numeric part of the needle (eg: ["23",
34, 45, "abc"]
in_array function returns true and array_search function returns int(2).
Test script:
---------------
<?php
$needle = '45x';
$haystack = ["23", 34, 45, "abc"];
//$test = 'g\'"';
//$test_array = ["g"];
$result = in_array($needle, $haystack );
var_dump($result);
$result = array_search($needle, $haystack );
var_dump($result);
Expected result:
----------------
functions have to return false
Actual result:
--------------
in_array: bool(true)
array_search: int(2)
