parse_str(parse_url($url, PHP_URL_QUERY), $array), see the manpage for parse_str for more info.

parse_str(parse_url($ url,PHP_URL_QUERY),$ array),有关详细信息,请参阅parse_str的联机帮助页。

#2

$href = 'http://www.somesite.com/index.php?url=var&file_id=var&test=var';

$url = parse_url($href);
print_r($url);
/* Array
(
    [scheme] => http
    [host] => www.somesite.com
    [path] => /index.php
    [query] => url=var&file_id=var&test=var
) */

$query = array();
parse_str($url['query'], $query);

print_r($query);
/* Array
(
    [url] => var
    [file_id] => var
    [test] => var
) */

It's actually a lot easier than writing any custom functions.

它实际上比编写任何自定义函数容易得多。

$queryStr = $_SERVER['QUERY_STRING'];

$ queryStr = $ _SERVER ['QUERY_STRING'];

#4

I'd use something like:

我会使用类似的东西:

preg_match_all('/(\?|&)([^=]+=[^&]*)/', $string , $matches);

then

print_r($matches[2]);
/*
Array
(
    [0] => url=var
    [1] => file_id=var
    [2] => test=var
)
*/

Hope it works 4 u.

希望它有效4你。
