it'll only echo $lowestrange if this expression is evaluated as true... wait, can you show your code with your changes?

How is $rowcats->followersrange being set?

you'd want to use: $rowCountUpdate -= ($updated);}

sure, if you did $a[++$i], it would increment $i first and set a new index $a[1] = 1

ok, so $a[0] will equal 1 what do you want it to do?

are you seeing an error from "select max(id) from persons;"

I guess prior to 4.0 🙄 @phppup please do an "explain persons;" and show us the results ...is your id field a string??

which version of mysql are you using? your version might not support MAX() try: $sql = "select id from persons order by id desc limit 1;" or: mysqli_insert_id($link);
