RE: [PHP] True || False ?

[Maxim Maletsky]

oops ...

I think I got too far from your original question:

yes,

function returnMeFoo($foo=0)
{
   if($foo)
      return true;
   return false;
}

if(returnMeFoo())
   echo 'you will not see this echo';
elseif(returnMeFoo(1))
   echo 'but if you see this means the function returned as true';

Cheers,
Maxim Maletsky

Yeah, sure you can,

if return is found in function it then exits it.

for example avoiding 'else' statements:


function returnMeFoo($foo=0)
{
   if(!$foo)
      return "Hey, you forgot to type a number in";
   if($foo>5)
      return "$foo is bigger then 5";
   if($foo<5)
      return "$foo is less then 5";

   return "Then, logically, $foo *IS* 5";
}


// then call this function as 

echo '<P>'.returnMeFoo(4);
echo '<P>'.returnMeFoo(5);
echo '<P>'.returnMeFoo(6);


And see how fun it is!

Cheers,
Maxim Maletsky

How does php handle true and false? Do they act as true booleans? 

Can I do?

function foo()
{
        return false;
}

Thanks,
