Parses str as if it were the query string
passed via a URL and sets variables in the current scope. If
the second parameter arr is present,
variables are stored in this variable as array elements instead.
Note:
Support for the optional second parameter was added in PHP 4.0.3.
Note:
The magic_quotes_gpc setting
affects the output of this function, as parse_str() uses
the same mechanism that PHP uses to populate the $_GET,
$_POST, etc. variables.
Example 1. Using parse_str()
<?php $str = "first=value&arr[]=foo+bar&arr[]=baz"; parse_str($str); echo $first; // value echo $arr[0]; // foo bar echo $arr[1]; // baz
parse_str($str, $output); echo $output['first']; // value echo $output['arr'][0]; // foo bar echo $output['arr'][1]; // baz
