What are the potential pitfalls or errors that can occur when using the imagerotate function in PHP?

One potential pitfall when using the imagerotate function in PHP is that the image may become distorted or lose quality if the rotation angle is not set correctly. To avoid this, it's important to ensure that the rotation angle is within the valid range of 0-360 degrees. Additionally, using the correct interpolation method can help maintain image quality when rotating. 

// Example of using imagerotate with proper angle and interpolation method
$image = imagecreatefromjpeg('image.jpg');
$angle = 90; // Rotate image by 90 degrees
$rotated_image = imagerotate($image, $angle, 0); // Use interpolation method 0 for best quality
imagejpeg($rotated_image, 'rotated_image.jpg');
imagedestroy($image);
imagedestroy($rotated_image);
