drupal 8 $_GET

In Drupal 8, $_GET is a superglobal variable that contains the query parameters from the URL. It is an associative array where the keys are the parameter names and the values are the corresponding values passed in the URL. You can access the value of a specific parameter by using its key in the $_GET array.

For example, if the URL is http://example.com/page?param1=value1&param2=value2, you can access the values of param1 and param2 using $_GET['param1'] and $_GET['param2'] respectively.

Please note that it is important to sanitize and validate the values obtained from $_GET before using them in your code to prevent security vulnerabilities such as SQL injection or cross-site scripting attacks.
