Verifying time in php [message #179375]

I have a form that has the following entry fields:
hours
minutes
seconds

I need the time in seconds and that works:
$realtime=$_POST['hours']*3600+$_POST['minutes']*60+$_POST['seconds'];

However people can fill out nothing or they could enter characters

What is the easiest way to verify if what the people filled out is
correct? I have tried, but I get lost in the if statements.

Extra difficult is that they must not fill out all three. Only one is
enough. e.g.
1 hour and no minutes or second gives 3600
1 hour, 1 minute and 1 second gives 3661
1 hour and 'X' should give an error.
All empty should give an error
empty hour 70 minutes and 75 seconds gives 4275.
Hours of more then 24 will be possible as well.
I might even add number of days.

If the last one gives an error, but it makes the life much easier, I can
live with that

It is the fact that they do not need to fill out all three that I am
stuck.

What I have tried is first to see if all are empty
Next try to see if each one is not a number
Then I need to figure out if there is a combination of some of it.

And that is when I get lost in the if statements and loops in loops.

I am sure there is an easy way to tell if all is nice and works well,
but how? Seaching google gave me transfering from seconds to H:i:s, but
that is not what I want.
