What is the best practice for transferring the value of $_GET['seite'] to $seite in the PHP code for effective pagination?

When transferring the value of $_GET['seite'] to $seite for pagination in PHP, it is best practice to sanitize and validate the input to prevent any security vulnerabilities or unexpected behavior. One way to achieve this is by using filter_input() function with FILTER_VALIDATE_INT filter option. This ensures that the value is an integer and safe to use in the pagination logic. 

// Sanitize and validate the input from $_GET['seite']
$seite = filter_input(INPUT_GET, 'seite', FILTER_VALIDATE_INT);

// Check if $seite is a valid integer, otherwise set a default value
if ($seite === false || $seite === null) {
    $seite = 1; // Set default page number
}

// Now $seite can be safely used in pagination logic
