How can PHP be used to sort uploaded images in a specific order?

When uploading images, PHP can be used to sort them in a specific order by renaming the files based on the desired order. One way to achieve this is by adding a prefix or suffix to the file names that represent the desired order. By sorting the file names in the desired order before displaying them, the images will appear in the specified sequence. 

// Array of uploaded image file names
$uploaded_images = ['image3.jpg', 'image1.jpg', 'image2.jpg'];

// Sort the array in the desired order
sort($uploaded_images);

// Rename the uploaded images based on the sorted order
foreach ($uploaded_images as $key => $image) {
    $new_name = 'image' . ($key + 1) . '.jpg'; // Rename based on desired order
    rename($image, $new_name); // Rename the file
}

// Display the images in the specified order
foreach ($uploaded_images as $image) {
    echo '<img src="' . $image . '" alt="Uploaded Image">';
}
