What are some best practices for utilizing PHP's graphic functions in web development projects?

When utilizing PHP's graphic functions in web development projects, it is important to follow best practices to ensure optimal performance and efficiency. One key practice is to properly handle error checking and validation to prevent unexpected behavior or security vulnerabilities. Additionally, optimizing image sizes and formats can help improve loading times and overall user experience.

// Example of resizing and displaying an image using PHP's graphic functions
$sourceImage = imagecreatefromjpeg('source.jpg');
$newWidth = 200;
$newHeight = 150;
$destinationImage = imagecreatetruecolor($newWidth, $newHeight);
imagecopyresampled($destinationImage, $sourceImage, 0, 0, 0, 0, $newWidth, $newHeight, imagesx($sourceImage), imagesy($sourceImage));
header('Content-Type: image/jpeg');
imagejpeg($destinationImage);
imagedestroy($sourceImage);
imagedestroy($destinationImage);
