Issue with $_GET being empty despite a valid URL parameter in PHP

I'm currently trying to pass a URL parameter to a PHP page on my local server, but I'm facing an issue with the $_GET superglobal that appears to be empty despite a valid URL parameter.

Here's a summary of the situation:

1. I have a link on my main page pointing to article.php with a URL parameter, for example: http://localhost:5500/blog/article.php?id=1

2. In article.php, I'm using $_GET['id'] to retrieve the value of the ID passed in the URL.

However, isset($_GET['id']) returns false, and var_dump($_GET) displays array(0), which is unexpected.

Example code in article.php:

<?php
include("config.php");

var_dump($_GET);  // Displays the data of the $_GET superglobal

if (isset($_GET['id'])) {
    $article_id = $_GET['id'];

    // ... (remaining code)
} else {
    echo 'Article ID not specified.';
}

$connexion->close();
?>

Here is my config.php :

<?php
$server = "localhost";
$user = "root";
$password = "****";
$database = "basename";

$connect = new mysqli($server, $user, $password, $database);

if ($connect->connect_error) {
    die("Connexion aborted : " . $connect->connect_error);
}
?>

What I've checked so far:

• The URL is correct.
• The link is correctly formed with a URL parameter.
• No apparent URL rewriting or redirection.

My question:

What could be the reasons for $_GET being empty despite a valid URL parameter? Is there anything I should check or additional configurations to consider?

Thank you in advance for your assistance!

My dev-server wasn’t able to pass URL parameters.
