How can the use of $_GET in PHP be optimized to handle cases where the last variable has no value?

When using $_GET in PHP, it is important to handle cases where the last variable in the query string has no value. This can be optimized by checking if the last variable is set but empty, and if so, removing it from the query string before processing the rest of the variables. 

// Check if the last variable is set but empty
if(end($_GET) === '') {
    array_pop($_GET); // Remove the last variable from the query string
}

// Process the rest of the $_GET variables
foreach($_GET as $key => $value) {
    // Your processing logic here
}
