Description:
------------
Following script will print '4-FAIL' using php 5.2.9 build and today's
snapshot php5.2-200903092130.
Following returns true where $k = int(0), which is wrong:
if ($k == 'abc')
echo "3-FAIL\n";
Also confirmed this is failing on 5.1.6.
Reproduce code:
---------------
<?php
$a = array(4);
if ($a[0] != '4')
echo "1-FAIL";
if ($a[0] != 4)
echo "2-FAIL";
if ($a[0] == 'abc')
echo "3-FAIL\n";
foreach ($a as $k => $v)
{
// $k is ONLY and ALWAYS ZERO (0)
var_dump($k);
var_dump($v);
if ($k == 'abc')
echo "4-FAIL\n";
if ($k === 'abc')
echo "5-FAIL\n";
if ($v == 'abc')
echo "6-FAIL\n";
}
Expected result:
----------------
Code should not print anything.
Only key is int(0) and only value is int(4)
