What is the difference between using $mem and $_GET["mem"] to pass variables in PHP?

Using $mem directly accesses a variable in PHP, while $_GET["mem"] accesses a variable passed through the GET method. It is generally safer to use $_GET["mem"] to pass variables in PHP as it helps prevent security vulnerabilities like injection attacks. By using $_GET["mem"], you are explicitly accessing variables passed through the GET method, making your code more secure. 

$mem = $_GET["mem"];
// Use $mem variable safely in your code
