[RESOLVED] Webcam Status script

ajd344

Hello!

I have a simple webcam set up that uploads a picture every 10 seconds. Expect, my computer is on at different times of the day. I would like a script that says "WEBCAM ONLINE" or "WEBCAM OFFLINE" depending on if the webcam has updated within the last 20 seconds.

I guess this could be done with checking the file for the last time it was updated and a IF statement.

$filename = 'current.jpg';
if (file_exists($filename)) {
   echo "" . date ("F d, Y - h:i:s A", filemtime($filename));
}

Here's some code that will check when my file has been modified.

I would love it if you could give my some tips, or write a script for me!

Thanks!

Can this be used for external webcam images (direct links), or do i have to change anything?

Since it's based on the file's modified time, it will work with any file that [man]filemtime/man supports.

Maybe so, but it doesn´t work for me.
I´m using it like this (external):

$filename = 'http://www.somehost.com/webcam.jpg';
if (file_exists($filename)) {
   echo "" . date ("F d, Y - h:i:s A", filemtime($filename));
}

Nor should it; the manual states that the HTTP/HTTPS wrappers don't support stat(), so naturally [man]filemtime/man will fail.

Ok! Is there another way to have a similar function for HTTP wrappers?

Not that I know of, unless the HTTP server returns a "Last-Modified" header for the file. Even if that were true, you'd probably have to retrieve and parse the HTTP headers yourself to determine the modified date.
