对于php中的循环数组

Question

Hello Guys how can i output this array using for loop? This code is working but it is not for loop.

  $a=array('Pol','Peter');
  $b=array('3.2','2.79');
  $c=array('1','1.4');
  $values = array($a,$b,$c);

  echo '<table border="1"><tr>';
  echo '<td>'.$values[0][0].'</td>';
  echo '<td>'.$values[1][0].'</td>';
  echo '<td>'.$values[2][0].'</td>>';
  echo '<tr><tr>';
  echo '<td>'.$values[0][1].'</td>';
  echo '<td>'.$values[1][1].'</td>';
  echo '<td>'.$values[2][1].'</td>';
  echo '</tr></table>';

Output:

 --------------------------------
 |   Pol   |  3.2     |   2.79  |
 |   Peter |  1       |   1.4   |
 --------------------------------

Help me how loop this output. Thanks in advance

You're looking for a for loop inside of a for loop.

The <table> tags should come outside of the outer loop, and the <tr> tags should come inside of the outer loop, but outside of the inner loop. Naturally, the <td> tags should come inside both.

This would look something like:

echo '<table border="1">';
for ($j = 0; $j < $c; $j++) {
  echo '<tr>';
  for ($i = 0; $i < count($values); $i++) {
    echo '<td>'.$values[$i][$j].'</td>';
  }
  echo '<tr>';
}
echo '</table>';

Hope this helps! :)
