Help with a home-grown function

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! -dant
