How can PHP beginners effectively read and display file names in a list menu?

To effectively read and display file names in a list menu, PHP beginners can use the glob() function to retrieve an array of file names in a directory. They can then iterate through the array and output each file name as a list item in an HTML unordered list.

<?php
$directory = "path/to/directory";
$files = glob($directory . "/*");

echo '<ul>';
foreach ($files as $file) {
    echo '<li>' . basename($file) . '</li>';
}
echo '</ul>';
?>
