What are some best practices for programming gdlib applications in PHP?

Issue: When programming gdlib applications in PHP, it is important to follow best practices to ensure efficient and secure code. One common best practice is to properly sanitize user input to prevent against malicious attacks such as SQL injection or cross-site scripting. Additionally, it is recommended to use gdlib functions correctly to optimize image processing and avoid memory leaks. Code snippet: 

// Sanitize user input before using it in gdlib functions
$userInput = $_POST['user_input'];
$cleanInput = htmlspecialchars($userInput);

// Example of using gdlib functions to process images
$image = imagecreatefromjpeg('image.jpg');
$width = imagesx($image);
$height = imagesy($image);

// Remember to free memory after processing images
imagedestroy($image);
