PHP Boolean Values like ASP

[Micha]

I'm traing to rewrite a part of code i've made in for ASP in PHP.

ASP:
If moneda = True Then
moneda = False
Else
moneda = NOT moneda
End If

This change the value of the variable from true to false and the other
way arround.

My problem is that PHP asumes that Null value is also False value.
So, I need three instances of the variable; when the variable was not
already user, to asume the Null value. If the value is Null, then to
change it to True, and when it is True to change it to false.
How can I solve this PHP misunderstud between Null and False value?

Thanks!

Try:

if moneda === true
moneda = false;
else
moneda = true;

if (moneda === true)

$bMoneda = $bMoneda ? false : true;

Do you know about the === and !== operators? They test for equality
of both value and type. So the expression (false === null ) evaluates
to false.
