Bug description:problem with in_array when mixing string and integer results
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 1:1
Cas 2:1
Cas n:1
Cas z:1
Cas Catalunya:1
Cas num no:
Cas num sÃ:1
Cas 1a:
