My code is finished and i'm trying to optimize it. I was wondering if the following 2 are the same or am I missing something that could potentially cause problems later on?
$this_awardid = !empty($_POST['awardid']) ? $_POST['awardid'] : null;
if (empty($this_awardid) ) {
...
} elseif (!empty($this_awardid)) {
...
}
I've optimized the code like so... I'm assuming that $this_awardid
it's NOT empty, so there is no need to verify.. Is this logic correct?
if (empty($this_awardid) ) {
...
} else {
...
}
You are defining $this_awardid
right there. It's guaranteed to exist. There's no need to use empty
for it at all, since all empty
does is suppress error messages for non-existing variables. You want error messages should you find $this_awardid
to be non-existent, since that means something's very wrong with your code.
Secondly, if (a) else if (!a)
is always redundant; you do not need to test for the inverse of the condition again, that is already contained in the if..else
itself.
So, all you need is:
if (!$this_awardid) {
...
} else {
...
}
