如何使用 $_SERVER['QUERY_STRING'] 在 url 中获取部分查询字符串

Question

I have a couple of url strings like below:

admin.php?filter_status=New

admin.php?filter_status=New&currentpage=2

and

admin.php?entry_search=Ready

admin.php?entry_search=Ready&currentpage=3

How can i grab always the value between ? and & ?

So: entry_search=Ready or filter_status=New

In case the url is" admin.php?entry_search=Ready&currentpage=3 ;

$_SERVER['QUERY_STRING'] gives me entry_search=Ready&currentpage=3 and it should always give me only entry_search=Ready

It will be the first in the $_GET superglobal, so:

$val = reset($_GET);
$key = key($_GET);

To use the query string:

parse_str($_SERVER['QUERY_STRING'], $array);
$val = reset($array);
$key = key($array);

If you really need a string then:

$result = "$key=$val";
