How can PHP scripts be optimized for processing and resizing images in bulk?

When processing and resizing images in bulk with PHP scripts, it is important to use efficient image processing libraries like GD or Imagick. Additionally, it is recommended to batch process the images to minimize the number of file system operations. Finally, consider optimizing the code by using caching mechanisms to avoid reprocessing already resized images. 

// Example PHP code snippet for processing and resizing images in bulk

// Set the directory containing the images
$directory = 'images/';

// Get all files in the directory
$files = glob($directory . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);

// Loop through each file and resize it
foreach ($files as $file) {
    // Load the image
    $image = imagecreatefromjpeg($file);

    // Resize the image
    $resizedImage = imagescale($image, 100, 100);

    // Save the resized image
    imagejpeg($resizedImage, $directory . 'resized_' . basename($file), 100);

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