How can PHP be used to dynamically generate file names based on the current date?

To dynamically generate file names based on the current date in PHP, you can use the date() function to get the current date and time in a specified format. You can then concatenate this date string with a desired file name or extension to create a unique file name based on the current date. 

// Get the current date in the format YYYY-MM-DD
$currentDate = date('Y-m-d');

// Concatenate the current date with a file name or extension
$fileName = 'file_' . $currentDate . '.txt';

echo $fileName; // Output: file_2022-01-01.txt
