Are there any best practices for creating and saving images in PHP?

When creating and saving images in PHP, it is important to follow best practices to ensure optimal performance and security. One common best practice is to use image manipulation libraries like GD or Imagick to handle image processing tasks. Additionally, it is recommended to validate user input to prevent malicious attacks like file uploads. Lastly, it is important to properly set file permissions and store images in a secure location on the server.

// Example of using GD library to create and save an image
$width = 200;
$height = 200;
$image = imagecreatetruecolor($width, $height);
$white = imagecolorallocate($image, 255, 255, 255);
imagefill($image, 0, 0, $white);
$filename = 'image.jpg';
imagejpeg($image, $filename);
imagedestroy($image);
