parse_url function
Let’s first understand the parse_url function, the official solution

Description:
mixed parse_url ( string $url [, int $component = -1 ] )

This function parses a URL and returns an associative array containing the various components that appear in the URL.
This function is not used to verify the validity of the given URL, only to break it into the parts listed below. Incomplete URLs are also accepted and parse_url() will try to parse them as correctly as possible.
The URL to parse. Invalid characters will be replaced with _.

Examples are as follows:

Copy code The code is as follows:

$url = "http://www.bkjia.com/welcome/";
$parts = parse_url($url);
print_r($parts);

array
(
[scheme] => http
[host] => www.jb51.net
[path] => /welcome/
)

Copy code The code is as follows:

function getParams()
{
$url = '/index.php?_p=index&_a=show&x=12&y=23';

$refer_url = parse_url($url);

$params = $refer_url['query'];

$arr = array();
if(!empty($params))
{
​​​​ $paramsArr = explode('&',$params);

foreach($paramsArr as $k=>$v)
           {
              $a = explode('=',$v);
             $arr[$a[0]] = $a[1];
         }

}

Call method

Copy code The code is as follows:

$arr = getParams();
print_r($arr);

The running results are as follows:

Copy code The code is as follows:

Array ( [_p] => index [_a] => show [x] => 12 [ y] => 23 )
