Are there best practices for preventing query string manipulation in PHP applications that do not involve converting all links to buttons?

Query string manipulation can be prevented in PHP applications by validating and sanitizing input data before using it in SQL queries or other sensitive operations. One approach is to use prepared statements with parameterized queries to prevent SQL injection attacks. Additionally, you can encode and validate query string parameters to prevent manipulation and ensure data integrity. 

// Example of validating and sanitizing query string parameters
$userId = filter_input(INPUT_GET, 'user_id', FILTER_VALIDATE_INT);

if ($userId === false) {
    // Handle invalid input
} else {
    // Use the sanitized $userId in your application logic
}
