Php & Gd

[ollmorris]

I have a script which uses a while loop with mysql to generate a graph however when I do a calculation in a while loop like $height = ceil ($highest / $myrow[hits]); I get an error.

Now this is just a calculation. I am not even using it to affect the GD output but I still get an error and I cannot figure out why. Is there something in GD which doesn't like this?

Thanks

well i think you forgot quotes besides hits:

change this:
$height = ceil ($highest / $myrow[hits]);

to this:
$height = ceil ($highest / $myrow['hits']);

and if that doesn't work let me know.

More likely there are occasions when $myrow[hits] is equal to 0. And thats impossible. You can't divide by 0 in maths.
