I saw my error, but I am still having problems. Being somewhat novice to PHP, I think my error might very well just be in my implementation of the function, as follows: function findMissingVals($workingArray) { $newcount = count($workingArray); for ($i = 0; $i <= $newcount; $i++) { if (empty($workingArray[$i])) { return 1; } } } if (findMissingVals($vars)) { if (!$var1) { ?> hi1 <? }; if (!$var2) { ?> hi2 <? }; if (!$var3) { ?> hi3 <? }; if (!$var4) { ?> hi4 <? }; if (!$var5) { ?> hi5 <? }; if (!$var6) { ?> hi6 <? }; } else { echo "hi"; } I never see "hi", even if I have an array as $vars as such: $vars = array("one","two","","four","five"); so I'm a bit confused. If you wouldn't mind taking another few minutes here, I would greatly appreciate it.
