PHP数组密钥＆amp;价值问题

Question

您好我在下面写了一个测试代码。

<?php
$url = 'http://localhost/events/result/cn_index.php?login';

print_r(parse_url($url));

echo parse_url($url, PHP_URL_PATH);


?>

输出

Array ( [scheme] => http [host] => localhost [path] => /events/result/cn_index.php [query] => login ) /events/result/cn_index.php

现在我插入了

下面的一行

echo array[query]; // I want to echo 'login', but failed.

如何获取'登录'的价值？

Answer 1

尝试：

$output = parse_url($url, PHP_URL_PATH);
echo $output['query'];

Answer 2

$parsed = parse_url($url);
echo $parsed['query'];
