>> it goes like this based on the number of categories
How do i get a simple array of the above like this
array('2' => 'Koffersenkisten','40'=> 'Muziek'...........etc); where 2 is the category_id and Koffersenkisten is the name
This function iterates over all items, and recurses when children are found. It passes the output array along at every invocation and appends to it:
function get_cats(array &$output, array $arr)
{
foreach ($arr as $item) {
$output[$item['category_id']] = $item['name'];
if (count($item['children'])) {
get_cats($output, $item['children']);
}
}
}
// start with empty result
$output = array();
get_cats($output, $a);
print_r($output);
This should work. Didn't test it.
$result = array();
function buildArray($array, $stack)
{
foreach($array as $item)
{
$stack[$item['category_id']] = $item['name'];
if(isset($item['children']) && count($item['children']) > 0)
foreach($item['children'] as $child)
buildArray($item['children'], &$stack);
}
}
buildArray($array, &$result);
print_r($result);
Here is a recursive solution (the array should be in $list before, the created array will be in $result after calling the create function):
function create($list, &$result) {
if (is_array($list) && !isset($list['category_id'])) {
foreach ($list as $element) {
create($element, $result);
}
} else {
$result[$list['category_id']] = $list['name'];
create($list['children'], $result);
}
}
create($list, $result);
Also see this example.
