Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
in_array does loose comparison, maybe you need to use the third argument of it.

Description:
------------
It affects all versions from 5.3 to 5.5.0.a.2.
Problems is when using in_array in array that mixes integer and numeric values
AND has alphanumeric keys f.e. 'name' in loose mode. Results are crazy and
unpredictable. Works fine when using numeric index.
When using in_array with strict work fine, but not here:
// Create an array like:
$st_array = array( 'name1' => 0,
'name2' => 1,
'name3' => '2',
'name4' => 'Catalunya Lliure');
// Then look with in_array and be surprised
echo 'Case 0:'.in_array('0', $st_array)."\n";
echo 'Case 1:'.in_array('1', $st_array)."\n";
echo 'Case 2:'.in_array('2', $st_array)."\n";
echo 'Case n:'.in_array('n', $st_array)."\n";
echo 'Case z:'.in_array('z', $st_array)."\n";
echo 'Case Catalunya:'.in_array('Catalunya', $st_array)."\n";
echo 'Case num no:'.in_array(3, $st_array)."\n";
echo 'Case num yes:'.in_array(1, $st_array)."\n";
// More in deep in the next box
Test script:
---------------
<?php
$st_array = array( 'name1' => 0,
'name2' => 1,
'name3' => '2',
'name4' => 'Catalunya Lliure');
echo 'Case 0:'.in_array('0', $st_array)."\n";
echo 'Case 1:'.in_array('1', $st_array)."\n";
echo 'Case 2:'.in_array('2', $st_array)."\n";
echo 'Case n:'.in_array('n', $st_array)."\n";
echo 'Case z:'.in_array('z', $st_array)."\n";
echo 'Case Catalunya:'.in_array('Catalunya', $st_array)."\n";
echo 'Case num no:'.in_array(3, $st_array)."\n";
echo 'Case num yes:'.in_array(1, $st_array)."\n";
// Please note the different case of 'Catalunya' working fine with
// numeric auto index
$st_array2 = array(2,'a','Catalunya Lliure');
echo 'Case 1a:'.in_array(3, $st_array2)."\n";
echo 'case 2a:'.in_array(2, $st_array2)."\n";
echo 'case 3a:'.in_array('2', $st_array2)."\n";
echo 'Case 4a:'.in_array('Catalunya', $st_array2)."\n";
echo 'Case 5a:'.in_array('Catalunya Lliure', $st_array2)."\n";
Expected result:
----------------
Expected:
Case 0: 1
Case 1: 1
Case 2: 1
Case n:
Case z:
Case Catalunya:
Case num no:
Case num yes: 1
Case 1a:
Case 2a: 1
Case 3a: 1
Case 4a:
Case 5a: 1
Actual result:
--------------
Cas 0:1
Cas 1:1
Cas 2:1
Cas n:1
Cas z:1
Cas Catalunya:1
Cas num no:
Cas num sÃ:1
Cas 1a:
cas 2a:1
cas 3a:1
Cas 4a:
Cas 5a:1
