If the second parameter arr is present, variables are stored in this variable as array elements instead. 注: Support for the optional second parameter was added in PHP 4.0.3. 注: To get the current QUERY_STRING, you may use the variable $_SERVER['QUERY_STRING'].

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. 注: Support for the optional second parameter was added in PHP 4.0.3. 注: 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. 例子 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 $arr[1]; // bazparse_str($str, $output);
echo $output['first']; // value
echo $output['arr'][0]; // foo bar
echo $output['arr'][1]; // baz?>
则
$str = $_SERVER['QUERY_STRING'];
$str = str_replace("=","[]=",$str);
parse_str($str);
print_r($id);
