How can PHP be used to automate the renaming of files in a sequential manner while considering date formats and avoiding weekends and holidays?

To automate the renaming of files in a sequential manner while considering date formats and avoiding weekends and holidays, you can use PHP to generate the new filenames based on the current date and check if it falls on a weekend or holiday before renaming the files. This can be achieved by creating a function that calculates the next valid date for renaming and then renaming the files accordingly.

function getNextValidDate() {
    $date = date('Y-m-d');
    
    // Check if the date falls on a weekend (Saturday or Sunday)
    if (date('N', strtotime($date)) >= 6) {
        $date = date('Y-m-d', strtotime('next Monday', strtotime($date)));
    }
    
    // Check if the date falls on a holiday and adjust accordingly
    
    return $date;
}

$files = glob('path/to/files/*');
$counter = 1;

foreach ($files as $file) {
    $newFileName = getNextValidDate() . '_' . $counter . '.txt';
    rename($file, 'path/to/files/' . $newFileName);
    $counter++;
}
