Question

I would like to get the last modified date of a remote file by means of curl. Does anyone know how to do that?

Answer 1

From php’s article:

<?php
// outputs e.g.  somefile.txt was last modified: December 29 2002 22:16:23.

$filename = 'somefile.txt';
if (file_exists($filename)) {
    echo "$filename was last modified: " . date ("F d Y H:i:s.", filemtime($filename));
}
?>

filemtime() is the key here. But I’m not sure if you can get the last modified date of a remote file, since the server should send it to you… Maybe in the HTTP headers?
