(condition ? true : false) and other boolean goodness

[filburt1]

It seems like a lot of people don't know about these two gems. The first is inline if. vB for some reason has it's own iif function which works like:

PHP Code:

$a = 1;
echo iif(($a == 1), "a is one", "a is not one"); // echoes "a is one" 


But you can just do this:

PHP Code:

$a = 1;
echo ($a == 1 ? "a is one" : "a is not one"); 


Also as a language construct it should be significantly faster than any user-defined function.


The other one is unnecessary ifs. Check this out:

PHP Code:

function stuff($s)
{
    if ($s == 50)
    {
        return true;
    }
    else
    {
        return false;
    }
} 


You can just do this:

PHP Code:

function stuff($s)
{
    return ($s == 50);
} 


Just sharing the goodness. I don't know why so few people know about these.
