Last updated date in PHP of current document

Question

How can I display the last time the current document was updated in PHP?

Answer 1

filemtime(); // file modified time

Example from PHP.net,

<?php
  // outputs e.g.  somefile.txt was last modified: December 29 2002 22:16:23.
  $file= 'somefile.txt';
  if (file_exists($file)) {
    echo "$file was last modified: " . date ("F d Y H:i:s.", filemtime($file));
  }
?>

Answer 2

If by "current document", you mean "script that is currently being executed", you can use something like this :

$timestamp = filemtime(__FILE__);
$date = date('Y-m-d H:i:s', $timestamp);
var_dump($date);

And the output is like :

string '2009-08-27 20:17:54' (length=19)

Which is the date and time it is right now in France ;-)

See filemtime to get the last modification date of a file, and date and it's formatting options to convert the timestamp returned by filemtime to something a human-being can understand.
