RE: RE: [PHP] cell iterations in loop

Right, I understand that if I use <td></td> it is blank space if I use <td>&nbsp;</td> it is an empty cell right now $length is set at 42 (this is arbitrary) and there needs to be two empty cells at the end of the last row. if length is 41 I will need 3 and 40 will need 4. but if I don't know what the value of $length is going to be on a dynamic page such as showing "x" amount of images from a folder. I need for the loop to know how many "<td>&nbsp;</td>" to echo out at the end depending on the $length; I apologize if I am not explaining this very well. I usually am quite concise.
