Description:
------------
---
From manual page: http://www.php.net/function.in-array#refsect1-function.in-array-returnvalues
---
Tested in 5.3 and 5.4 with the results that a numeric and string index aren't found in an array. Returns false when it should be true. There is no "Undefined index" error raised.

Test script:
---------------
testcase1.php
=============
<?php
  $musketeers = array("Noble"=>"Athos","Priest"=>"Aramis"
                     ,"Dandy"=>"Porthos","Hero"=>"d'Artagnan"); 
  $search = "Dandy";
    
  if (in_array($search,$musketeers))
    print "[Is Found] [".$musketeers[$search]."]\n";
  else
    print "[Not Found][".$musketeers[$search]."]\n";    
?>

testcase2.php
=============
<?php
  $musketeers = array("Athos","Aramis","Porthos","d'Artagnan");
  $search = "2";
  
  if (in_array($search,$musketeers))
    print "[Is Found] [".$musketeers[$search]."]\n";
  else
    print "[Not Found][".$musketeers[$search]."]\n";
?>

Expected result:
----------------
It should return true when finding the index value in the array.

Actual result:
--------------
Doesn't return true when finding the index value in the array, but doesn't raise an Undefined index error.
