Re: RE: RE: [PHP] cell iterations in loop

ahhhhh, i got it... ok, try this: $length is arbitrary... $x is your counter... do the loop as before, but each time through the loop, $loopcount++; So, if you do the loop 5 times, $loopcount == 5. Then, at the end, $length - ($loopcount*$x) gives you the amount of <td> </td>'s to echo. Put another for loop with these parameters after you've printed your normal td's...you could do this all in one for loop, and would just need some more if statements... i think this is what you need...let me know how it goes... -jack ----- Original Message ----- From: "Jerry Lake" <jerryl@europa.com> Date: Thursday, April 26, 2001 5:20 pm Subject: RE: RE: [PHP] cell iterations in loop > Right, I understand that > if I use <td></td> it is blank space > if I use <td> </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.
