Hello, all -
I've been looking around for a function that would tell me if a $value
in a $key=>$value array was empty, and I could not find one. So I
decided to make my own. Even if I am re-inventing the wheel, I thought
that the practice might be good for me.
However, my function doesn't *quite* work, and I'm having a difficult
time finding out why. The code is as follows:
function findMissingVals($workingArray) {
$newcount = count($workingArray);
for ($i = 0; $i <= $newcount; $i++) {
if (empty($workingArray['$i'])) {
return 1;
}
}
}
So it takes in $workingArray as an array, runs a loop, checks $i, yada
yada. The thing is, that sometimes the function does not return 1, even
when it should.
I was hoping some experienced eyes could take a gander at this and give
me some pointers.
Thanks!
