Get URL headers in PHP

February 5, 2023

So, let’s say I’m a client entering this URL on my blog website: https://blogbyme.com/post?id=1.
I want the server to see that URL and customize the page based off what post it is.
The main question is – when the request is made, how do I grab the id header’s value to send the correct blog post?

Right now I’ve got this far.

if (!function_exists('getallheaders')) {
    function getallheaders() {
    $headers = [];
    foreach ($_SERVER as $name => $value) {
        if (substr($name, 0, 5) == 'HTTP_') {
            $headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))))] = $value;
        }
    }
    return $headers;
    }
}

and that’s still not working.

>Solution :

Use the superglobal of PHP $_GET:

echo $_GET["id"];

You can get the full request URI from:
