How can PHP be used to sort files based on their upload date?

To sort files based on their upload date using PHP, you can use the `filemtime()` function to get the last modification time of each file and then sort the files based on this timestamp. You can achieve this by creating an array of file paths, getting the modification time of each file, sorting the array based on these modification times, and then iterating through the sorted array to display the files in the desired order. 

$dir = 'uploads/';
$files = scandir($dir);
$files = array_diff($files, array('..', '.'));

usort($files, function($a, $b) use ($dir) {
    return filemtime($dir . $a) < filemtime($dir . $b);
});

foreach($files as $file) {
    echo $file . '<br>';
}
