[Resolved] Output Format Problems (table cells)

Kudose

Hello all.

I've never been any good at this sadly enough. Maybe someone could shed some light as to why this happens:

When $tot is even, everything runs smooth. When $tot is odd, every few rows (starting at $i == 3) it puts terminates a row prematurely. The problem seems to be sporadic instead of intermitten, but only on odd $tot counts.

Hope that makes sense.

$tot = count($pteam);
              $row = $pteam;
               for($i=0; $i < $tot; $i++){
                if($i % 2 == 0)
                  echo '<tr>';

              echo '<td align="left">';
              echo '<img src="'.$row[$i]['picture'].'" border="0" align="absMiddle" width="115" height="105">';
              echo '</td>';
              echo '<td';
                echo ($i !== $tot - 1) ? '' : ' colspan="3"';
              echo '>';
                echo '<p><b>Name: </b>'.$row[$i]['name'].'<br>
                      <b>Phone: </b>'.$row[$i]['phone'].'<br>
                      <b>E-Mail: </b>'.$row[$i]['email1'].'<br></p>';
              echo '</td>';

            if($tot % $i == 1 || $i == $tot - 1)
              echo '</tr>';
          }

TIA. 🙂

It's not the ternary operator either, I tried removing it to no avail.

A couple of questions.

for($i=0; $i < $tot; $i++) {

if($i % 2 == 0) echo '<tr>';

do something<td></td>

if($tot % $i == 1 || $i == $tot - 1) echo '</tr>';

}

I do not know about this expression:
if ($i % 2 == 0) { }
Tell me, I do not know what this does. I want to learn.
Thanks

% is the modulus operator.

Basically it returns the remainder from a divide.

i.e.

10 % 2 = 0

10 % 3 = 1

10 % 5 = 0

So...

if $i modulus 2 equals zero I want to start a new row.

if $i modulus 2 equals one OR $i equals my total number of rows ($tot - 1 (since $i started at 0 and $tot started at 1)) then I want to end that row.

You probably knew the So... part, but I typed it just in case.

Okay.
you should put in those expressions on a paper:

$i $i%2 next
0 0 ?
1 1 ?
2 0 ?
3 1 ?
and so on

maybe this way, you will see what happens, and where goes wrong

Your suggestion made my brain hurt. 🙁

I actually started doing it.

I glanced over an old script I had and came across my problem (which I didnt see the first time over).

//wrong
if($tot % $i == 1 || $i == $tot - 1)

//right
if($i % 2 == 1 || $i == $tot - 1)

Thanks for your help anyways. 🙂
