PHP Navigation Classification for the Great God

The following is an array of 10

Now it is necessary to write a function parameter that is the 10 heap array required to return an array $return

$return [' top '] is those top-level navigation array 3 array
Array (3) {.... Top Navigation ' Discussion download official area array:}

$return [' child '] is what those sub-navigation arrays Note is also the 3 array that corresponds to the top-level array
Array (3) {
[0] = = Array (3) {...... Help Exchange Technology share a comprehensive discussion array.}
[1] = = Array (2) {...... e-book Software array:}
[2] = = Array (2) {...... Feedback program published array:}
}
Array 1 belongs to the sub-navigation array of the discussion array
Array 2 is a sub-navigation array of the downloaded array
Array 3 is the sub-navigation array of the official area array

Now it is necessary to write a function parameter that is the 10 heap array required to return an array $return

$return [' top '] is those top-level navigation array 3 array
Array (3) {.... Top Navigation ' Discussion download official area array:}

$return [' child '] is what those sub-navigation arrays Note is also the 3 array that corresponds to the top-level array
Array (3) {

[1] = = Array (2) {...... e-book Software array:}

function getFormate($arr){    $top = $child = array();    foreach($arr as $val){        if($val['pid'] == 0){            $top[] = $val;        }else{            $child[ $val['pid'] ][] =    $val;         }    }    return array('top' => $top, 'child' => array_values($child) );}

This should be what you need.
