我试图获取每个 URL 参数并从头到尾显示它们,但我希望能够在页面上的任何位置显示任何参数.我怎样才能做到这一点?我必须在我的脚本上添加或修改什么?
I'm trying to grab each URL parameter and display them from first to last, but I want to be able to display any of the parameters anywhere on the page. How can I do this? What do I have to add or modify on my script?
这是一个 URL 值示例.
Here is an example of a URL value.
http://www.localhost.com/topics/index.php?cat=3&sub1=sub-1&sub2=sub-2&sub3=sub-3&sub4=sub-4
这是我的 PHP 脚本.
Here is my PHP script.
$url = $_SERVER['QUERY_STRING'];
$query = array();
if(!empty($url)){
foreach(explode('&', $url) as $part){
list($key, $value) = explode('=', $part, 2);
$query[$key] = $value;
}
}
您不需要手动执行此操作,PHP 已经在 $_GET 全局变量中提供了此功能:
You don't need to do that manually, PHP already provides this functionality in the $_GET global variable:
<?php
foreach($_GET as $key => $value)
echo $key . " : " . $value;
?>
