php 使用 parse_str 把查询字符串解析到变量中

<?php
$url='http://shop.m.taobao.com/shop/coupon.htm?seller_id=1888136962&activity_id=a3cc6e4ad26e4f0ea2ba144d2b60364d';
$parse_url=parse_url($url);
print_r($parse_url);

parse_str($parse_url['query'],$output);

print_r($output);
?>

输出:
Array
(
    [scheme] => http
    [host] => shop.m.taobao.com
    [path] => /shop/coupon.htm
    [query] => seller_id=1888136962&activity_id=a3cc6e4ad26e4f0ea2ba144d2b60364d
)
Array
(
    [seller_id] => 1888136962
    [activity_id] => a3cc6e4ad26e4f0ea2ba144d2b60364d
)
