超越PHP - Exceed PHP: parse_str

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.

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 $arr[1]; // baz parse_str($str, $output); echo $output['first']; // value echo $output['arr'][0]; // foo bar echo $output['arr'][1]; // baz ?>

You can perform the opposite of this function if you like with a function
like I've built below:

    /**
     * Reverse of parse_str(). 
Converts array into
     * string with query format
     */
   
function query_str ($params) {
        $str = '';
        foreach
($params as $key => $value) {
            $str .= (strlen($str) <
1) ? '' : '&';
            $str .= $key . '=' .
rawurlencode($value);
        }
        return ($str);
   
}
