How can PHP be used to read files from a folder and determine their modification date?

To read files from a folder and determine their modification date in PHP, you can use the `glob` function to get an array of file paths in the folder, and then use the `filemtime` function to get the last modification time of each file.

$folder_path = 'path/to/folder/';

$files = glob($folder_path . '*');

foreach ($files as $file) {
    $modification_date = date("Y-m-d H:i:s", filemtime($file));
    echo "File: $file | Modification Date: $modification_date <br>";
}
