OFF TOPIC:

Renegade, thank you for posting the link to your site, as the last bit of code you had gave me a solution to something I had looked for in PHP: using the value of a variable to name a variable you want. (using the $$'s). I have been wanting to use that, I was used to being able to use "eval()" in another language.

(For those reading this and not knowing what I am talking about, try this example)

<?php
    $greg = \"This is Greg\";

    $varName = \"greg\";

    echo \"the variable '$varName' = {$$varName} \n\";

    // GIVE YOU:
    // the variable 'greg' = This is Greg 
?>

Where the heck is this in the PHP manual???? LOL

Again, thanks for the post, it lead me to an answer I have wanted for a while.

-Greg

(PS. yeah, i thought of asking about it on here, but never got around to it LOL)

HTTP 1.0 (RFC 1945, section 10.10) and 1.1 (RFC 2616, section 14.29) have
an defined an optional "Last-Modified" header in the HTTP Response.
Syntax:
Last-Modified: Wed, 17 Nov 2004 03:08:16 GMT

If your (remote) server outputs this header, you can open a TCP connection
the remote server, send a HTTP Request, then read the HTTP Response.
From there, you can parse out the Last-Modified header and play your sound.

Example HTTP Request:

GET /showthread.php?t=26729 HTTP/1.0
Host: webmaster-forums.net

'
Example HTTP Response:

HTTP/1.1 200 OK

You can try a "last updated" piece of code that I usually use:

$last_updated = $page_title . " was last updated: " . date ("F d Y", filemtime($page . ".php"));'

Found at my site
