Looping through array of unlimited children and display to a table - php

Question

I don't have any idea how to loop through this array and display it to an HTML table. Child data are dynamic and can be unlimited. Anyone can give me a clue? Thanks!
(
[0] => Array
(
[Discount] => Array
(
[id] => 8
[parent_id] => 0
[lft] => 1
[rght] => 6
[name] => Discount 1
[value] => 25
)
[children] => Array
(
[0] => Array
(
[Discount] => Array
(
[id] => 10
[parent_id] => 8
[lft] => 2
[rght] => 5
[name] => Child of D1
[value] => 32
)
[children] => Array
(
[0] => Array
(
[Discount] => Array
(
[id] => 11
[parent_id] => 10
[lft] => 3
[rght] => 4
[name] => The 1.1.1
[value] => 65
)
[children] => Array
(
)
)
)
)
)
)
)
I know I can't just do:
foreach($discounts as $discount){
echo "<div>{$discount['Discount']['name']}</div>";
}

Answer 1

Try this
foreach ($Discount as $children => $value) {
echo "<div>{$discount['Discount']['$children']['name']}</div>";
}

You will need recursion to properly generate the HTML. Here is an example that I hope is helpful. This isn't exactly HOW you'll want to generate the final HTML but this should get you started on the right track:
$data = array(
0 => array(
'discount' => array(
'id' => 8,
'parent_id' => 0,
'lft' => 1,
'rght' => 6,
'name' => 'Discount 1',
'value' => 25,
),
'children' => array(
0 => array(
'discount' => array(
'id' => 10,
'parent_id' => 8,
'lft' => 2,
'rght' => 5,
'name' => 'Child of D1',
'value' => 32,
),
'children' => array(
0 => array(
'discount' => array(
'id' => 11,
'parent_id' => 10,
'lft' => 3,
'rght' => 4,
'name' => 'The 1.1.1',
'value' => 65,
),
'children' => array(),
)
)
)
)
)
);
$html = getHtml($data);
/**
* This function is called recursively to generate the necessary HTML
* #param array $data
*/
function getHtml(array $data)
{
// This is your base conditon to end the recursion. It stops once it hits an empty children array
if (empty($data)) {
return;
}
$data = $data[0]; // will have to tweak this if you have more than 1 element per array
$html = sprintf('<div id="%d" name="%s">', $data['discount']['id'], $data['discount']['name']);
$html .= getHtml($data['children']); // this recursive call generates inner HTML
$html .= '</div>';
return $html;
}
// See the result
var_dump($html);
