PHP Array Key＆value問題

Question

嗨，我寫了如下的測試代碼。

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

print_r(parse_url($url)); 

echo parse_url($url, PHP_URL_PATH); 


?> 

輸出

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

現在我插入下面

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

行如何獲得的 '登錄' 的價值？

Answer 1

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

Answer 2

嘗試：

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