I have looked through a few answers on here but that don't seem to utilise this method?
I have an array of items, and the items are objects. The object can have a key which is 'children' and 'children' is an array of objects etc.
Is there a way to achieve this?
Example:
Array
(
[1] => stdClass Object
(
[id] => 1
[name] => Steve King
[image] => upload/shop/fe7a66254e4249af2b0093efca75a914.jpg
[parent] => 0
[children] => Array
(
)
)
[2] => stdClass Object
(
[id] => 2
[name] => Eden Hall
[image] => upload/shop/064f60a98deba612e437ac549f1dc05d.jpg
[parent] => 0
[children] =>Array
(
[1] => stdClass Object
(
[id] => 1
[name] => Steve King
[image] => upload/shop/fe7a66254e4249af2b0093efca75a914.jpg
[parent] => 0
[children] => Array
(
)
)
)
[3] => stdClass Object
(
[id] => 3
[name] => Paula Johnson
[image] => upload/shop/1492a323090afbad07c35cf93fe6bdda.jpg
[parent] => 0
[children] => Array
(
)
)
[4] => stdClass Object
(
[id] => 4
[name] => Ethan Watson
[image] => upload/shop/677c720333af33bc58d0684d79918e03.jpg
[parent] => 0
[children] => Array
(
)
)
[5] => stdClass Object
(
[id] => 5
[name] => Abigail Adams
[image] => upload/shop/da1734277322fc3b2e84a9ddbcc2e2f1.jpg
[parent] => 0
[children] => Array
(
)
)
Assign an array of objects under $array.
Solution 1: json_encode an array of objects to make it a json and then converting an json into associative array.
$result=json_decode(json_encode($array),true);
array_walk_recursive($result, function($value,$key){
print_r($value);
print_r($key);
});
Solution 2: Iterating over array and type casting each object as array.
array_walk($array,function(&$value,$key){
$value=(array) $value;
});
array_walk_recursive($array, function($value,$key){
print_r($value);
print_r($key);
});
You always can implement a custom recursive iterator for certain data structure. It can be a more flexible solution. For example:
class MyIterator extends \IteratorIterator implements
\RecursiveIterator
{
public function hasChildren()
{
$current = $this->current();
if (is_array($current) and $this->key() === 'children') {
return true;
}
return is_object($current);
}
public function getChildren()
{
/* $current is array (for key 'children') or \stdClass obj*/
$current = $this->current();
return new MyIterator(new \ArrayObject($current));
}
}
$rii = new \RecursiveIteratorIterator(new MyIterator(new
\ArrayObject($data)));
foreach ($rii as $key => $value) {
print_r($key);
print_r($value);
}
