How to dynamically split result into nested table - php

Question

Hi I'm having trouble trying to split my db object result into the correct table for display.
Basically I'm trying to acheive this
<div class="panel"> $row->skill_group
<table class="collapse">
<thead>
<tr>
<th>$row->name</th>
</tr>
</thead>
<tbody>
<tr>
<td>$row->skill_name</td>
</tr>
<tr>
<td> $row->competency_name </td>
</tbody>
</table>
</div>
There can be many unique skill_groups and many skill_names but each person and their competency should only be displayed once for each skill.
My mysql returns the correct data however I can't figure out how to loop over the result so that I can split it in between the table that is nested from the div container.
For example the mysql result would be
======================================================================
| skill_group_name | skill_name | competency_name | name
======================================================================
| PHP Frameworks | Codeigniter | Working Knowledge | User name1
| PHP Frameworks | CakePHP | No Knowledge | User name1
| Database | T-SQL | Working Knowledge | User name2
======================================================================
and I need to fit it into the html structure above.
The result I'm after is
======================================================================
PHP Frameworks
======================================================================
| Codeigniter | Working Knowledge | User name1
| CakePHP | No Knowledge | User name1
======================================================================
Database
======================================================================
| T-SQL | Working Knowledge | User name2
======================================================================
I have managed to get the grouping of the skill_group sorted with:
if($row->skill_group_name != $skill_group_name)
{
echo '<div class="panel-heading"><a href="#" data-target=".skill'.++$counter.'" data-toggle="collapse">' . $row->skill_group_name;
$skill_group_name = $row->skill_group_name;
echo '</a></div>';
}
But I'm missing how to write the loops for the data table itself, how do I do this?

As I commented, I think you should save to an array, then implode() the sections:
//Just some fake data
$array[] = array('PHP Frameworks','Codeigniter','Working Knowledge','User name1');
$array[] = array('PHP Frameworks','CakePHP','No Knowledge','User name1');
$array[] = array('Database','T-SQL','Working Knowledge','User name2');
// Loop through the data
foreach($array as $row) {
// Save the table column html to array
$section[$row[0]][] = '<tr><td>'.$row[1].'</td><td>'.$row[2].'</td><td>'.$row[3].'</td></tr>';
}
// Loop through the section array you made
foreach($section as $title => $all) {
// Wrap it
echo '<div>'.$title;
// Implode
echo '<table>'.implode(PHP_EOL,$all).'</table>';
echo '</div>';
}
