What are the potential performance implications of reading directories with a large number of images in PHP?

Reading directories with a large number of images in PHP can lead to performance issues due to the time it takes to iterate through all the files. To mitigate this, you can use the glob() function with a specific pattern to only retrieve image files, reducing the number of files to process. 

$images = glob('path/to/images/*.jpg');
foreach ($images as $image) {
    // Process each image file here
}
