Help With PHP and timestamp

I set this up:

$time1=time();

Later On,

$time2=time();

if I:

echo $time1 -> 1109145600
echo $time2 -> 1109201240

But if I

echo($time2 - $time1) -> -1109145600

Why? Why is it not 55640?

Can Anyone help?

Can't be.

But try echo((int)$time2 - (int)$time1);

you sure your echo statement is exactly as shown? It should print 55640, unless you misspelled your variable, or maybe forgot to put brackets around your math statement.

Try doing:

Code:

$time1=time();

$time2=time();

$result=$time2-$time1;

echo $result;

That should guarantee you the result you want. You shouldn't have to use typecasting (int) if you assigned your variables using the time() function, it will return an integer.

My guess is that you've made a type on the echo?

ie PHP is calculating "0-$time1"

by the way, if you are timing your application, use microtime() as it is more precise (milliseconds).

Damn, I should be in bed. That's exactly what it was doing.

0-$time1

mistyped var.

Thanks for the help guys.
