如何在WHILE循环中使用FOREACH循环创建几列

Question

PROBLEM

I am pulling data from my database...using a WHILE loop & I want the returned data to be coupled into "scalable in size" groups.

I thought that by using a FOREACH LOOP inside of the while loop, I could accomplish this, apparently I thought wrong..ARRG!

CODE

$queryCatz = mysqli_query($cxn, "SELECT DISTINCT idBrand FROM Products ");
while($list_of_xtras = mysqli_fetch_array($queryCatz)) {     

    $cur = 0;
    $rowNum = 1;
    foreach($list_of_xtras as $key => $value){

        if($cur == 0){
            echo '<ul style="border:2px solid purple;" class="theROW' . $rowNum . '">';
        }

        echo '    <li style="list-style:none;">' . $value. '</li>';

        if($cur == 2)
        {
            echo '</ul>';
            $cur = 0;
            $rowNum++;
        }
        else
        {
            $cur++;
        }
    }


}       

After 3 hours of trying to fix this, and at the risk of exposing my very obvious lack on understanding, I humbly bow before the collective minds of SO....and shout...HELP, I've coded and can't get up!

I might be off track. I think you want:

$queryCatz = mysqli_query($cxn, "SELECT DISTINCT idBrand FROM Products ");
while($list_of_xtras = mysqli_fetch_array($queryCatz)) {     
  $rowNum = 1;
  echo '<ul style="border:2px solid purple;" class="theROW' . $rowNum . '">\r\n';
  for($curr=0; $curr<2; $curr++){
    echo '\t<li style="list-style:none;">' . $list_of_xtras[$curr] . '</li>\r\n';
  }
  echo '</ul>';
  $rowNum++;
}

Seems like you're just looking for 2 results, so I don't know if FOREACH is best here. Maybe just a FOR loop.

Edit, after I saw your comment. Sounds like you want to wrap 10 results in a UL. To do that it would be something like:

$rowNum = 1;
echo '<ul style="border:2px solid purple;" class="theROW' . $rowNum . '">\r\n';
$queryCatz = mysqli_query($cxn, "SELECT DISTINCT idBrand FROM Products ");
while($list_of_xtras = mysqli_fetch_array($queryCatz)) {     
  if($rowNum % 10 == 0){
    echo '</ul><ul style="border:2px solid purple;" class="theROW' . $rowNum . '">\r\n';
  }
  echo '\t<li style="list-style:none;">' . $list_of_xtras[0] . '</li>\r\n';
  $rowNum++;
}
echo "</ul>\r\n";
