What is the purpose of the PHP script provided in the forum thread?

The purpose of the PHP script provided in the forum thread is to sanitize user input data to prevent SQL injection attacks. This is done by escaping special characters in the input data before using it in SQL queries. 

// Sanitize user input data to prevent SQL injection
function sanitize_input($input) {
    $input = trim($input);
    $input = stripslashes($input);
    $input = htmlspecialchars($input);
    return $input;
}

// Example usage
$user_input = $_POST['user_input'];
$sanitized_input = sanitize_input($user_input);
