How to Subtract time ???

[npsari]

Hello there,

 

I echo from my database the two variables $time1 & $time2

 

Here is the format of the Time

$time1 = 08:24:02

$time2 = 20:34:47

 

I want to create an IF funtiocn which will echo the following...

 

If the time difference is more than 15 minutes: Sorry, the time difference is more than 15 minutes

If the time difference is less than 15 minutes: Your session is still active

 

But i dont know how to subtract Time

 

$result = $time2 - $time1 ;
If($result > '15') {
Echo "Sorry, the time difference is more than 15 minutes";
}else{
Echo "Your session is still active";
}

 

I think this is wrong... Please show me how...

You will have to split the numbers and then figure it out.

i would say use

 

$time1 = "08:24:02";
$time2 = "20:34:47";

$t1 = strtotime($time1);
$t2 = strtotime($time2);

 

the make the sum the value returned is in seconds so 15 minutes would be 900

strtotime converts to a unix timestamp with out enough information to do so?  I guess it just assumes the current day.

I think you are right it assumes the current day I am using the same on my login security it works for that ok.
