# parse_str

(PHP 3, PHP 4 )

parse_str -- Parses the string into variables

## Description

void parse_str ( string str [, array arr])

Parses `str` as if it were the query string passed via an URL and sets variables in the current scope. If the second parameter `arr` is present, variables are stored in this variable as an array elements instead.

> Note: Support for the optional second parameter was added in PHP 4.0.3.

> Note: To get the current QUERY_STRING, you may use the variable $_SERVER['QUERY_STRING']. Also, you may want to read the section on variables from outside of PHP.

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

    ?>
