Please, someone ca help me with that?

I want to unset the parent array key if any value inside of that array is null;

e.g.

array
(
    0 => array
    (
        'type' => 'Main'
        'phone' => '11 555-1423'
        'foo' => array(
            0 => (
                'bar' => ''
            )
         )

    )
    1 => array
    (
        'type' => 'Personal'
        'phone' => ''
        'foo' => array()
    )
)

In this case I want to unset [0][foo] and [1].

I think this is exactly what you want

function fclear(&$arr, $del){
    foreach($arr as $key=>&$val){
        if($val == '')
            return true;
        if(is_array($val)){
            $del = fclear($val, false);
                if($del == true)
                    unset($arr[$key]);
        }
    }
}

fclear($myarr,false);

you can look at the Code Sample, run it and see result.
