Check if a file is older than 5mins old

Anon

I wish to be able to check whether a file is older than 5mins old.

Basically I have a webcam that uploads a screenshot every 30seconds called webcam.jpg and i want to know whether that file is older than 5mins old (ie. the webcam is off). How would i go about doing this?

Thankyou,

Jamie

I found that, but i still dont know exactly how i would code it. How do i compare the filemtime date/time with the current date/time -5mins?

filemtime(string) returns a UNIX timestamp, so does time()

These are in seconds.

5 mins is 5 * 60 = 300 seconds.

diff = time() - filemtime('webcam.jpg');

if (diff > 300)
{
// do something
}
