IF OR and Know the result???

[itsallgood]

Hi guys,

Is there another way to do the following...

if(isset($varA) || isset($varB)){
	include_once('var_file.php'); // only needs to be included if one of the above vars are set.
    if(isset($varA)){
    	$theVar = $varA;
    }else{
    	$theVar = $varB;
    }

$endValue = functionInFile($theVar);
}

As the variables are already checked if they exist in the IF statement itself - is there anyway to do away with the inner IF statements to see which one was true?

-- Also, as you can see i have an "include" in my if statement - am i write that this will only be included if the if statement is true? Saving my page having to load external files that are otherwise unneeded?

Thanks again guys!

I don't know that this really gains you anything, but it is more compact. 🙂

$thisVar = (isset($varA)) ? $varA : (isset($varB)) ? $varB : null;
if (isset($thisVar)) {
   include_once ('var_file.php'); // only needs to be included if one of the above
   $endValue = functionInFile($theVar);
}
