global just makes it available within the function, you then call the
variable as normal

using your code:

$j = 0;
function doThis($tempVariable) {
    global $myArray;
    if ($myArray[$j] == $tempVariable) {
        echo "whatever";
    }
    $j++;
}

Then how wuld I declare the global as the condition of an if?

$j = 0;
function doThis($tempVariable) {
    if (global $myArray[$j] == $tempVariable) {
        echo "whatever";
    }
    $j++;
}

Thanks,

John
