[status] => 2
[title] => bananer
[breadcrumb] => /bananer
[slug] => /bananer
[2] => Array
(
[id] => 2
[parent_id] => 1
[status] => 2
[title] => sub bananer
[breadcrumb] => /bananer/sub bananer
[slug] => /bananer/sub-bananer
)
[3] => Array
(
[id] => 3
[parent_id] => 1
[status] => 0
[title] => sub bananer 2
[breadcrumb] => /bananer/sub bananer 2
[slug] => /bananer/sub-bananer-2
)
)
[4] => Array

[id] => 4
[parent_id] => 0
[status] => 0
[title] => appelsin
[breadcrumb] => /appelsin
[slug] => /appelsin
[5] => Array

[id] => 5
[parent_id] => 4
[status] => 2
[title] => sub appelsin
[breadcrumb] => /appelsin/sub appelsin
[slug] => /appelsin/sub-appelsin

[6] => Array

[id] => 6
[parent_id] => 4

Answer 1

Try this:
function deleteIt(&$array)
{
foreach($array as $key => &$value)
{
if (is_numeric($key)) deleteIt($value);
if (isset($value['status']) && !$value['status']) unset($array[$key]);
}
}
This runs through the array recursively while handing references down so that the original array is modified while deleting. Notice the & in the deleteIt function prototype and in the foreach.

Something like this may help
function parse($var)
{
foreach($var as $key => $val)
{
if( is_array($val) )
{
parse($val)
}
else
{
if($key == 'status' && $val ==0 )
{
// do something here
}
}
}
}

You can do something that's highly specialized such as:
function stripBadStatus($array) {
foreach($array as $k=>$arr) {
if($arr['status'] == 0) {
unset($array[$k]);
} else if(is_array($arr)) {
foreach($arr as $deepk=>$deeparr) {
if($deeparr['status'] == 0) {
unset($array[$k][$deepk]);
}
}
}
}
return $array;
}
