What are the potential challenges of formatting a gallery using PHP compared to HTML?

One potential challenge of formatting a gallery using PHP compared to HTML is the need to dynamically generate the gallery structure based on the images available. This can be solved by using PHP to loop through the image directory and generate the necessary HTML code for each image. 

<?php
$dir = 'images/';
$files = scandir($dir);

echo '<div class="gallery">';
foreach ($files as $file) {
    if (in_array($file, array(".", ".."))) continue;
    echo '<img src="' . $dir . $file . '" alt="' . $file . '">';
}
echo '</div>';
?>
