What are the best practices for sorting files based on modification date in PHP?

When sorting files based on modification date in PHP, the best practice is to use the `filemtime()` function to get the modification timestamp of each file, then sort the files based on this timestamp. This can be achieved by creating an array of file paths and modification timestamps, sorting the array based on the timestamps, and then iterating through the sorted array to process the files in the desired order. 

// Get list of files in directory
$files = glob('path/to/directory/*');

// Create array to store file paths and modification timestamps
$fileData = array();
foreach($files as $file) {
    $fileData[$file] = filemtime($file);
}

// Sort files based on modification date
arsort($fileData);

// Process files in sorted order
foreach($fileData as $file => $timestamp) {
    // Process file here
}
