How can PHP beginners effectively learn and implement image rotation without using a database for storing image data?

To rotate images in PHP without using a database, beginners can utilize the GD library functions provided by PHP. By loading the image, rotating it using the `imagerotate()` function, and then saving the rotated image, beginners can achieve image rotation functionality without the need for a database. 

<?php
// Load the image
$image = imagecreatefromjpeg('image.jpg');

// Rotate the image 90 degrees
$rotated_image = imagerotate($image, 90, 0);

// Save the rotated image
imagejpeg($rotated_image, 'rotated_image.jpg');

// Free up memory
imagedestroy($image);
imagedestroy($rotated_image);
?>
