Simple variable check problem

[nobrain]

I have this code:

 

if (!$value) {

$ok=0;

break;

}

 

It is supposed to check if a variable is not empty and, if it is, then fail.  The problem is that sometimes the variable is 0 -- then it also fails.  I need it to fail if the variable is empty but not if it has a value of 0.

 

Thanks!

Thought is was simple, guess not?
