Question

I have an multidimensional array which I’m trying to output as a table,
here is my array;

$marksarray=     
array(3) {
      [0]=>
      array(2) {
        [0]=>
        string(1) "8"
        [1]=>
        string(1) "0"
      }
      [1]=>
      array(2) {
        [0]=>
        string(1) "9"
        [1]=>
        string(1) "1"
      }
      [2]=>
      array(2) {
        [0]=>
        string(2) "13"
        [1]=>
        string(1) "2"
      }
    }

So far I have my code like this;

echo "<table><tr><td>Question</td><td>Rating</td></tr>";
     foreach ($marksarray as $mks){
         foreach ($mks as $qid=>$rate){
            echo "<tr><td>".$qid."</td><td>".$rate."</td></tr>";
          }
    }
echo "</table></div>";

But my output is;

What is that i’m doing wrong?

You’ve got one too many foreach‘s going on there. Try this instead:

echo "<table><tr><td>Question</td><td>Rating</td></tr>";
     foreach ($marksarray as $mks){
        echo "<tr><td>".$mks[0]."</td><td>".$mks[1]."</td></tr>";
    }
echo "</table></div>";

For future reference, it makes your code far easier to understand if you use an array of associative arrays with meaningful keys. e.g.

$marksarray = array(
    array('qid' => 8, 'rating' => 0), 
    array('qid' => 9, 'rating' => 1), 
    array('qid' => 13, 'rating' => 2)
);

Then your loop would look like this:

foreach ($marksarray as $mark){
    echo "<tr><td>".$mark['qid']."</td><td>".$mark['rating']."</td></tr>";
}

Better still, you should use MVC (Model, View, Controller) and pass this data into a view…but that’s another subject entirely.
