# parse_str

(PHP 3, PHP 4, PHP 5)

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 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: 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.

> 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 ?>`
