Display columns with rows in php table - php

Question

Hey guys I need your help, I have this table
and I want to shows like this FIDDLE, really I don't know how to do this because sometimes just exist two columns(prov_name ) and sometimes exist more that two rows please help me if you can !
Hope you understand me. Thanks so much !
In this way I can be able to select data from Joomla.
$db =& JFactory::getDBO();
$query = 'SELECT prov_name FROM provprices where CA_id = '.$CA_id;
$db->setQuery($query);
$result = $db->loadObjectList();
$prov_name = $result[0];
echo $prov_name->prov_name;

First off, in order for your data to be presented like that obviously it must be grouped accordingly.
The first row is, the prov_name's, so you can use GROUP BY or you cal also do it in PHP. Based of the sample data, it should have from 1 to 6.
Then the second row is just a simple unitval and totval according to how many prov_name's.
Third is the and the rest is the grouping of the values. See Example:
$db = new PDO('mysql:host=localhost;dbname=DATABASE_NAME;charset=utf8', 'USERNAME', 'PASSWORD');
$data = array();
$results = $db->query("SELECT * from YOUR_TABLE_NAME");
while($row = $results->fetch(PDO::FETCH_ASSOC)) {
$data[$row['prov_name']][] = $row;
}
$keys = array_keys($data);
$size = count($keys);
$vals = array();
// grouping:
// if there are six (cam1 to cam6)
// then group them by cam1, ... to cam6, then repeat until theres no more left
while(count($data) > 0) {
foreach($keys as $key) {
if(!empty($data[$key])) {
$vals[] = array_shift($data[$key]);
} else {
unset($data[$key]); // remove them if empty
}
}
}
$vals = array_chunk($vals, $size); // split them by how many prov_names
?>
<table border="1" cellpadding="10">
<!-- PROV NAMES -->
<tr><?php for($x = 1; $x <= $size; $x++): ?>
<th colspan="2"><?php echo "prov_name $x"; ?></th>
<?php endfor; ?></tr>
<!-- unitval totvals -->
<tr><?php for($x = 1; $x <= $size; $x++): ?>
<td>unitval</td><td>totval</td>
<?php endfor; ?></tr>
<!-- the grouped values -->
<?php foreach($vals as $val): ?>
<tr>
<?php foreach($val as $v): ?>
<td><?php echo $v['unitval']; ?></td>
<td><?php echo $v['totval']; ?></td>
<?php endforeach; ?>
</tr>
<?php endforeach; ?>
</table>

I think you must do this first,
try looping to show prov_name in horizontal,
and then you fetch again in query with
"SELECT * FROM table_test where prov_name = '$prov_name'"
in Variable $prov_name you must have a value with CAM2 or CAM3 .etc
sorry just a logic :)
