Question

I am trying to use for loops to create a table which dynamically returns something like this: Note how the td content have been arranged

<table>
 <tr>
  <td>1</td>
  <td>3</td>
  <td>5</td>
  <td>7</td>
  <td>9</td>
 </tr>
 <tr>
  <td>2</td>
  <td>4</td>
  <td>6</td>
  <td>8</td>
  <td>10</td>
 </tr>
</table>

among What I have tried so far is

$row=2;
$col=20;
$x=0;
echo '<table>';
for($i=0;$i<$row;$i++){
   echo '<tr>';
     for($k=0;$k<$col;$k++)
     {
        echo '<td>'.echo $x+=1.'</td>';
     }
   echo '</tr>';

}

In this case I get something different and which is not what I want.

<table>
    <tr>
     <td>1</td>
     <td>2</td>
     <td>3</td>
     <td>4</td>
     <td>5</td>
    </tr>
    <tr>
     <td>6</td>
     <td>7</td>
     <td>8</td>
     <td>9</td>
     <td>10</td>
    </tr>
  </table>

Kindly someone help me map this.Thanks

Answer 1

<?php 
  # how high to count
  $count = 10;

  # how many rows in the table
  $rows = 2;

  # figure out how many columns
  $columns = ceil($count/$rows);

  # could also go the other way and declare there to be 5 columns and then 
  # divide to get the rows, but since you're counting down the columns, 
  # I thought this made more sense.  Either way.

?><table><?php 

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

 ?><tr><?php

    for ($j=0; $j<$columns; ++$j) {

      # calculate which number to show in column $j of row $i.  Each column adds
      # $rows numbers to the total, while each row just adds one more.  And we
      # want to start at 1 instead of 0.
      $n = $j * $rows + $i + 1;

      ?><td><?= $n ?></td><?php 
    }

  ?></tr><?php

  }
?></table>
