Question

I am trying to create a table from array retrieved from database.
array is multidimensional and dynamic.
my sample array is
Array
(
[0] => Array
(
[licensee] => AmazonUK
[totalCounts] => 2
[netRoyalty] => 0.01006506
[month] => 2017-05-01
)
[1] => Array
(
[licensee] => AppleMusicGB
[totalCounts] => 52
[netRoyalty] => 43.39295886
[month] => 2017-04-01
)
[2] => Array
(
[licensee] => AppleMusicHK
[totalCounts] => 2
[netRoyalty] => 6.71799264

[netRoyalty] => 328.95685302
[month] => 2017-03-01
)

[licensee] => iTunesEU
[totalCounts] => 4
[netRoyalty] => 1.00737582
[month] => 2017-02-01
)
[12] => Array
(
[licensee] => iTunesGB
[totalCounts] => 8
[netRoyalty] => 0.91430508
[month] => 2017-03-01
)
[13] => Array
(
[licensee] => iTunesUS
[totalCounts] => 2
[netRoyalty] => 99.69851988
[month] => 2017-06-01
)
)
I want to create a table like :
licensee as horizontal heading
month as vertical heading
totalCounts and netRoyalty as totalCounts/netRoyalty under their respective licensee
jsfiddle of sample table is included.
jsfiddle
EDIT :
what i tried is
<table id="table1" class="table table-striped table-hover table-fw-widget">
<thead>
<tr>
<?php
foreach($distributorReportAnalysis as $distreportkey => $distreportval){
?>
<th><?php echo $distreportval[licensee]; ?></th>
<?php
}
?>
</tr>
</thead>
<tbody>
<?php
foreach($distributorReportAnalysis as $distreportk => $distreportv){
?>
<tr class="odd gradeX">
<th><?php echo date('M Y',strtotime($distreportv[month])); ?></th>
<?php
foreach($distreportv as $reportk => $reportv){
?>
<td><?php echo $distreportv['totalCounts']."/".round($distreportv['netRoyalty']); ?></td>
<?php
}
?>
</tr>
<?php
}
?>
</tbody>
</table>

this is a quick example of how you could extract values with array_map. Actually a foreach works too, array_map is particularly useful if you want to modify the original array.
So the idea here is to organize the data before display, here getting the headers and value by month separately. For your display, you'll still have to place the good value to the good position in the array, but it is sorted by headers value now, so that will be easy.
<?php
$arr = [
0 => [
'licensee' => 'AmazonUK',
'totalCounts' => '2',
'netRoyalty' => '0.01006506',
'month' => '2017-05-01',
],
1 => [
'licensee' => 'AppleMusicGB',
'totalCounts' => '52',
'netRoyalty' => '43.39295886',
'month' => '2017-04-01',
],
];
$headers = [];
$rows = [];
function customExtract($element){
global $headers, $rows;
//an array for your headers
if(!in_array($element['licensee'], $headers)){
$headers[] = $element['licensee'];
}
//another for the rows by month
if(!isset($rows[$element['month']])){
$rows[$element['month']] = [];
}
$rows[$element['month']][$element['licensee']] = $element['totalCounts'] . '/' . $element['netRoyalty'];
//you can also transform the original array element or not (if not you just return it)
return $element;
}
$arr = array_map('customExtract', $arr);
var_dump($headers);
echo'<br />';
var_dump($rows);
?>
the result:
array(2) { [0]=> string(8) "AmazonUK" [1]=> string(12) "AppleMusicGB" }
array(2) { ["2017-05-01"]=> array(1) { ["AmazonUK"]=> string(12) "2/0.01006506" } ["2017-04-01"]=> array(1) { ["AppleMusicGB"]=> string(14) "52/43.39295886" } }
