In PHP, there are many ways to get the parameters in the URL, the simplest of which is to use the Parse_url function directly, he can easily and quickly automatically parse the URL parameters and values and save to the corresponding array, the other method is basically a regular expression to operate.

Let's take a look at 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.

Copy the Code code 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 the Code code 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];
}
}
return $arr;
}
Calling methods
