What is the difference between file modification date and upload date in PHP?

The file modification date refers to the last time the content of a file was changed, while the upload date refers to the time when the file was uploaded to the server. To get the file modification date, you can use the filemtime() function in PHP, while to get the upload date, you may need to store this information separately in your database or application logic. 

// Get the file modification date
$filename = 'example.txt';
$modification_date = filemtime($filename);
echo "File modification date: " . date("Y-m-d H:i:s", $modification_date);

// To get the upload date, you may need to store this information separately in your database or application logic
