Question

I have a table chart. Lets say 5 by 5. I run a loop such as

<table>
    <tbody>
     <?php for ($i = 0; $i < 5; $i += 5) {
           echo "<tr>
              <td>one box</td>
              <td>one two</td>
              <td>one three</td>
              <td>one four</td>
           <tr>";
      }?>
     </tbody>
</table>

It creates a table such as

 |      |      |      |      |       |
 -------------------------------------
 |      |      |      |      |       |
 -------------------------------------
 |      |      |      |      |       |
 -------------------------------------
 |      |      |      |      |       |
 -------------------------------------
 |      |      |      |      |       |
 -------------------------------------

Now I have mysql data I load for my purposes and I need it to put the data in respectively so the table looks like

 |      |      |      |      |       |
 -------------------------------------
 |      |      |      |      |       |
 -------------------------------------
 |      | Res 1|      |      |       |
 -------------------------------------
 |      |      |      | Res 3|       |
 -------------------------------------
 |      |Res 4 |      |      |  Res 2|
 -------------------------------------

How would I do this? I have 50 results and need to fill the results into the correct column and row. I need to do some sort of if(results[0-50][‘id’] == rowcolumnid) echo the results for the correct table while doing the for loop.

Edit: Here is my full code.

    <table id="schedule">
        <tbody>
            <?php
            $time = mktime(0, 0, 0, 1, 1);
            for ($i = 28800; $i < 62200; $i += 1800) { ?>
             <tr id="row<?php echo $i; ?>">
                <td id="hour">
                    <?php 
                    printf('%1$s',date('g:i a', $time + $i)); 
                    ?>
                </td>
                                    <td id="sunday"></td>
                                    <td id="monday"></td>
                                    <td id="tuesday"></td>
                                    <td id="thursday"></td>
                                    <td id="friday"></td>
                                    <td id="saturday"></td>
            </tr>
            <?php } ?>
        </tbody>
    </table>

My mysql results are in datetime format that I’m going to use to propogate the table.

Results:

ID| EVENT NAME | DATEOFEVENT
1 | event name | 2012-11-20 12:00:00
2 | event name | 2012-11-21 13:30:00
3 | event name | 2012-11-22 13:00:00
4 | event name | 2012-11-23 11:00:00
5 | event name | 2012-11-24 08:00:00

etc.

I can do a strtotime of the dates and a date command to match.

If you first fetch the data (or if it is sorted if you first fetch the first data), then you can just iterate over the data when you match the hour/time that you iterate over to draw the table.

As an example, I’ve chosen to display only one column that represents 5 hours (1-5) of which some can be matched. Those that are matched, are stored in an array and made available as an iterator (ArrayIterator):

$data = [3,5];
$datas = new ArrayIterator($data);
$datas->rewind();

Matched hours are represented with 1, unmatched ones with 0:

echo "+---+---+\n";

foreach(range(1, 5) as $hour)
{
    if ($hasData = ($datas->valid() and $datas->current() === $hour)) {
        $datas->next();
    }
    $hasData = (int) $hasData;


    echo "| $hour | $hasData |\n";
    echo "+---+---+\n";
};

Output:

+---+---+
| 1 | 0 |
+---+---+
| 2 | 0 |
+---+---+
| 3 | 1 |
+---+---+
| 4 | 0 |
+---+---+
| 5 | 1 |
+---+---+

This works perfectly if the data from the data is available as an iterator (often the case, for mysql_* you need to write you one) and if it is sorted.

Even this is only a single list here, for a table this works actually equally because a table is just a different form of representing the data.
