There are many tutorials based on Array, which you need to go through it for basic understanding.
Quick Start
Code
<?php
$arr["2016-10-26"] = ['abc'=> 0, 'def'=> 0, 'xyz'=> 0];
$arr["2016-10-27"] = ['abc'=> 0, 'def'=> 0, 'xyz'=> 0];
print_r($arr);
?>
<table>
<tr>
<th>Date</th>
<th>abc</th>
<th>def</th>
<th>xyz</th>
</tr>
<?php foreach($arr as $key=>$val){?>
<tr>
<td><?=$key;?></td>
<td><?=$val['abc']?></td>
<td><?=$val['def']?></td>
<td><?=$val['xyz']?></td>
<?php }?>
</tr>
</table>
Output
Array ( [2016-10-26] => Array ( [abc] => 0 [def] => 0 [xyz] => 0 )
[2016-10-27] => Array ( [abc] => 0 [def] => 0 [xyz] => 0 ) )
Date abc def xyz
2016-10-26 0 0 0
2016-10-27 0 0 0
