Description:
------------
---
From manual page: http://www.php.net/function.parse-str
---
The first part of the current example prints $arr, which is never declared:

<?php
$str = "first=value&arr[]=foo+bar&arr[]=baz";
parse_str($str);
echo $first;  // value
echo $arr[0]; // foo bar
echo $arr[1]; // baz

Expected result:
----------------
Instead, it should be:
<?php
$str = "first=value&arr[]=foo+bar&arr[]=baz";
$arr = parse_str($str);
echo $first;  // value
echo $arr[0]; // foo bar
echo $arr[1]; // baz
