How can I change array for the menu? - php

Question

There is an array of data obtained by Rest API. I am trying to make a menu from this data, but for this I need to convert it with regard to nesting (I think this is done in a loop)
I rummaged through the Internet, everywhere recursion with usual numeric id, and my id is a string, I tried to do it myself through foreach, it turned out
foreach ($elements as $item){
$thisRef = &$ref[$item['objectId']];
$thisRef['parent'] = &$item['parent'];
$thisRef['name'] = $item['property']['ru']['value'];
$thisRef['objectId'] = $item['objectId'];
$thisRef['number'] = $item['number'];
$thisRef['duration'] = $item['duration'];
$thisRef['object'] = $item['object'];
$thisRef['listorder'] = $item['listorder'];
if($item['parent'] == 0) {
$items[$item['objectId']] = &$thisRef;
} else {
$ref[$item['parent']]['child'][$item['objectId']] = &$thisRef;
}
}
print_r($items);
The cycle written by me works poorly, it displays a branch only up to level 2
array of $elements spread below in print_r and var_export
[objectId] is the id of the item
[parent] is the parent of the element, it refers to the parent's objectId, if it is empty or equal to 0, then it has no parent
A big request to offer a solution with unlimited nesting.
I hope you are will help me.

Answer 1

Try this:
function cascadeElements($elements, &$result, $index = 0, $parent = null) {
$next = function () use ($elements, &$result, $index, $parent) {
cascadeElements($elements, $result, ++$index, $parent);
};
if ($index >= count($elements)) {
return;
}
$element = $elements[$index];
if (!$parent && $element['parent'] !== null) {
return $next();
}
if ($parent && $element['parent'] !== $parent['objectId']) {
return $next();
}
$element['children'] = [];
cascadeElements($elements, $element['children'], 0, $element);
$result[$element['objectId']] = $element;
return $next();
}
You use it like this:
$result = [];
cascadeElements($data, $result);
$result will get filled with objectId keyed hierarchical list of elements where each element has it's children under children key.
This function should work for infinite amount of nesting.

Answer 2

I believe you want to loop through all of the items, current item as $current. If it has a parent, find the parent object $parent and then add the item to the parent's children array($parent.children[] = $current).
// Loop through all
foreach ($elements as $current) {
if (!empty($current['parent'])) {
// Loop through all if they have a parent
foreach ($elements as $parent) {
// Add $current as a child if this is the parent
if ($current['parent'] === $parent['objectId']) {
$parent['children'][] = $current;
}
}
}
}
If you only want parents in the array, you might be able to unset() or just make a new array by checking if the element doesn't have a parent.
