How can the use of the glob function simplify the process of working with image files in PHP, as suggested in the forum thread?

Working with image files in PHP can be cumbersome when dealing with multiple files in a directory. The glob function simplifies this process by allowing us to easily retrieve an array of file paths that match a specified pattern, such as all image files in a directory. This can streamline tasks like looping through image files for processing or displaying. 

// Get all image files in a directory
$images = glob('path/to/directory/*.jpg');

// Loop through the array of image file paths
foreach ($images as $image) {
    // Process or display each image as needed
}
