I want to get the date info of a specific file:

program name = what-time-changed-php.php

<?php
$filename = '/wp-content/themes/cat_c21/functions.php';
if (file_exists($filename)) {
echo "$filename was last modified: " . date ("F d Y H:i:s.", filemtime($filename));
}
?>

I type it in at the root site address:

http:// <sitename>/what-time-changed-php.php

..but this is coming up with a blank display. :(

What am I doing wrong?

invalid or no html? have you looked at the resulting page's source in your browser?

also, for security reasons, you'd be better off to have $filename contain only the file's name... put the path in another one and do not output it at all... then connect the two when needed...

php can be executed directly. I don't need to call it within html.

Meanwhile, after adjusting the script without the "if.." and thus forcing an output, I would get, the output:

Last modified: December 31 1969 19:00:00.

..which is php-speak for "file not found".

:(

another one and do not output it at all... then connect the two
when needed...

What do you mean "do not output it at all"? How would I see the result otherwise?

I just want to produce a report of "last modified" dates of files in specific directories. And if that works, have the script email the output on a schedule. But the above is a first step.

How would this would be a security risk?

i know :)

i didn't say you did but if you expect a browser to properly render the output, it should be in proper html format ;)

i'm saying that if you want to keep your server's directory layout secret to prevent possible hacking access and fore-knowledge of your setup, do not output the path of the file...

then why be messing with looking at the output in a browser?

How would this would be a security risk?

because it would publish the path to those with possibly nefearious desires...
