PHP get URL parameter method summarize _php skill

The example of this article describes the PHP get URL parameter method. Share to everyone for your reference. Specifically as follows:

There are many ways to get the parameters in the URL in PHP, the simplest of which is to use the Parse_url function directly, he can easily and quickly automatically resolve the URL parameters and values and storage to the corresponding array, other methods are basically regular expressions to operate.

Parse_url function
Let's take a look at the Parse_url function, the official solution

Description
Mixed Parse_url (string $url [, int $component =-1])

This function resolves a URL and returns an associative array containing the various components that appear in the URL.
This function is not used to verify the legality of a given URL, but to decompose it into the sections listed below. An incomplete URL is also accepted, and Parse_url () tries to parse it as correctly as possible.
The URL to resolve. Invalid characters will be replaced with _.

Examples are as follows:

Copy Code code as follows:

$url = "http://www.jb51.net/welcome/";
$parts = Parse_url ($url);
Print_r ($parts);

Array
(
[Scheme] => http
[Host] => www.jb51.net
[Path] =>/welcome/
)

You can also write an algorithm yourself!

Copy 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;
}

Call method

Copy Code code as follows:

$arr = Getparams ();
Print_r ($arr);

The results of the operation are as follows:

Copy Code code as follows:

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