Description:
------------
combination of array with zero as the second key and foreach loop is causing false equality.  See simple example below...




./configure --with-apxs=/work/st/daemons/apache/bin/apxs --disable-libxml --prefix=/work/st/daemons/php --with-zlib --disable-dom --disable-simplexml --disable-xml --disable-xmlreader --disable-xmlwriter --without-pear




Reproduce code:
---------------
<?php /*>*/;
$value = 'T';
$options = array('T' => 'TBD', '0' => 'Level 0', 
		 '1' => 'Level 1', '2' => 'Level 2'
		 );

var_dump($options);
echo '<br>';
foreach($options as $val => $txt) {

  if($value == $val) {  
    echo "$value == $val<br>" ;
  }
}

?>

Expected result:
----------------
I expect to ONLY see T == T.

Actual result:
--------------
result is:

T == T
T == 0
