How can PHP access parameters passed in the URL?

To access parameters passed in the URL in PHP, you can use the $_GET superglobal array. This array contains key-value pairs of all the parameters passed in the URL. You can access a specific parameter by using its key within the $_GET array. 

// Example URL: http://example.com/index.php?id=5

$id = $_GET['id']; // Accessing the 'id' parameter passed in the URL
echo $id; // Output: 5
