3 time loop in present like html table? - php

Question

I have an array:
$A = array(
'A'=>
array('a1'=>array(1,2,3),
'a2'=>array(1,2,3),
'a3'=>array(1,2,3)),
'B' =>
array('b1'=>array(1,2,3),
'b2'=>array(1,2,3),
'b3'=>array(1,2,3)),
'C');
How Can I use loop to present data (html table ):
-----------------------------
| | time1| time1 | time2 |
----------------------------
A | 3 | 6 | 8
-----------------------------
a1 | 1 | 2 | 2
-----------------------------
a2 | 1 | 2 | 3
-----------------------------
a3 | 1 | 2 | 3
----------------------------
B
b1
b2
b3
C
I am trying( get the total && display C instead 0):
echo '<table border="1">';
echo "<tr><td></td><td>time1</td><td>time2</td><td>time3</td></tr>";
foreach ($A as $key=>$main){
echo '<tr>';
echo "<td>$key</td>";
echo "<td>???</td>";
echo "<td>???</td>";
echo "<td>???</td>";
echo '</tr>';
foreach ($main as $k=>$sub) {
echo '<tr>';
echo "<td>$k</td>";
foreach ($sub as $kk =>$val) {
echo "<td>$val</td>";
}
echo '</tr>';
}
}
echo '</table>';

<?php
$A = array(
'A'=>
array('a1'=>array(1,2,2),
'a2'=>array(1,2,3),
'a3'=>array(1,2,3)),
'B' =>
array('b1'=>array(1,2,3),
'b2'=>array(1,2,3),
'b3'=>array(1,2,3)),
'C'=> null); // in your case it won't be key it will be value
echo '<table border="1">';
echo "<tr><td></td><td>time1</td><td>time2</td><td>time3</td></tr>";
foreach($A as $key => $value)
{
echo "<tr><td>".$key."</td>";
if(!is_array($value))
continue;
echo "<td>".implode("</td><td>", findSum($value))."</td></tr>";
foreach($value as $cKey => $cValue){
echo "<tr><td>".$cKey."</td>";
echo "<td>".implode("</td><td>", $cValue)."</td>";
}
echo "\n";
}
function findSum($value)
{
if(!is_array($value))
return array(0);
$result = array();
foreach($value as $childValue)
{
foreach($childValue as $cKey => $cValue)
$result[$cKey] = isset($result[$cKey]) ? $result[$cKey] + $cValue : $cValue;
}
return $result;
}
