如何检索当前页面名称和任何变量

I'm using basename($_SERVER['PHP_SELF']) but this only gives me the page name e.g.

http://www.mysite.com/helloworld.php?name=Dan

I can only get "helloworld.php".

I need "helloworld.php?name=Dan"

There is also $_SERVER['QUERY_STRING'], and $_SERVER['REQUEST_URI'] and many more.

In your case, you can get it like:

$whatiwant = $_SERVER['REQUEST_URI'];

or

$whatiwant = $_SERVER['PHP_SELF']."?".$_SERVER['QUERY_STRING'];

$full_link = "http://" . $_SERVER[HTTP_HOST] . $_SERVER[REQUEST_URI];

Just try with:

$_SERVER['REQUEST_URI']

it will returns you:

/helloworld.php?name=Dan

But if you do:

trim($_SERVER['REQUEST_URI'], '/')

you will get:

helloworld.php?name=Dan

Use the variable query string if available:

echo isset($_SERVER["QUERY_STRING"]) ? $_SERVER["QUERY_STRING"] : "";

You can use this

$_SERVER['REQUEST_URI];

You can read more about $_SERVER here.

If you want to get all the query strings from the URL. You can use this:

echo basename($_SERVER['REQUEST_URI']);

$_SERVER['REQUEST_URI'] will returned helloworld.php?name=Dan.

You can try print_r($_SERVER) for getting more from SERVER variable.
