How can PHP scripts be optimized to improve performance and efficiency when processing image uploads and rotations?

To optimize PHP scripts for processing image uploads and rotations, it is essential to use efficient image processing libraries such as GD or Imagick. Additionally, resizing images before uploading them can help reduce the processing load. Caching processed images can also improve performance by avoiding repetitive processing. 

// Example code snippet using GD library to resize and rotate an image before uploading

// Load the image
$image = imagecreatefromjpeg('example.jpg');

// Resize the image
$newWidth = 200;
$newHeight = 200;
$resizedImage = imagescale($image, $newWidth, $newHeight);

// Rotate the image
$rotateAngle = 90;
$rotatedImage = imagerotate($resizedImage, $rotateAngle, 0);

// Save the processed image
imagejpeg($rotatedImage, 'processed_image.jpg');

// Free up memory
imagedestroy($image);
imagedestroy($resizedImage);
imagedestroy($rotatedImage);
