Question

I am trying to determine the difference between the date of a file in a directory and the current date, I have tried calculating two ways:

 $fileUnixTimeDate = filemtime($file);
 $fileFormattedDate = date('m/d/y',filemtime($file));

 $todayUnixTimeDate =  time();
 $todayFormattedDate = date('m/d/y',time());

 $unixDifference = $todayUnixTimeDate - $fileUnixTimeDate;
 $formattedDifference =  $todayFormattedDate - $fileFormattedDate;

This is the result for two files in the directory:

Answer 1

I can only assume that you’re trying to get the number of days’ difference:

$fileUnixTimeDate = filemtime($file);
$todayUnixTimeDate =  time();

$unixDifference = $todayUnixTimeDate - $fileUnixTimeDate;
$daysDifference = $unixDifference/86400;

Note: 86400 because there are 86400 seconds in 1 day.

$daysDifference would contain the amount of days.
