无法从cakephp中的多维数组中删除数组键

I want to delete array index which contain rating 0 here is my array

array(
    (int) 0 => array(
        'Gig' => array(
            'id' => '1',
            'rating' => (int) 5
        )
    ),
    (int) 1 => array(
        'Gig' => array(
            'id' => '3',
            'rating' => (int) 9
        )
    ),
    (int) 2 => array(
        'Gig' => array(
            'id' => '4',
            'rating' => '0'
        )
    )
)   

and what I did

for($i = 0; $i<count($agetGigsItem); $i++)
{
if($agetGigsItem[$i]['Gig']['rating']==0)
{
unset($agetGigsItem[$i]);   
}
$this->set('agetGigsItem', $agetGigsItem);
}

i also try foreach loop but unable to resolve this issue.

foreach ($agetGigsItem as $key => $value) { 

    if ($value["Gig"]["rating"] == 0) { unset($agetGigsItem[$key]); }

}

    I think you need to reupdate your array.

    foreach ($agetGigsItem as $key => $value) {
    if ($value["Gig"]["rating"] != 0) 
    {
    unset($agetGigsItem[$key]); 
    }
    $this->set('agetGigsItem', $agetGigsItem);
    }
