What are some best practices for handling server requests in PHP?

One best practice for handling server requests in PHP is to validate user input to prevent security vulnerabilities such as SQL injection or cross-site scripting attacks. This can be done by sanitizing and validating input data before processing it. Additionally, using prepared statements when interacting with a database can help prevent SQL injection attacks. 

// Example of validating user input and using prepared statements
$user_input = $_POST['user_input'];

// Sanitize and validate user input
$clean_input = filter_var($user_input, FILTER_SANITIZE_STRING);

// Prepare a SQL statement using prepared statements
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
$stmt->bindParam(':username', $clean_input);
$stmt->execute();
