PHP如何从多维数组中删除数组并创建新数组

Question

我有这个数组:

array(3) { 
["cod"]=> array(3) { 
    ["code"]=> string(3) "cod" 
    ["title"]=> string(38) "Pay on delivery" 
    ["sort_order"]=> string(1) "1" 
    } 
["pp_standard"]=> array(3) { 
    ["code"]=> string(11) "pp_standard" 
    ["title"]=> string(6) "PayPal" 
    ["sort_order"]=> string(1) "1" 
    } 

["bank_transfer"]=> array(3) { 
    ["code"]=> string(13) "bank_transfer" 
    ["title"]=> string(25) "bank_transfer" 
    ["sort_order"]=> string(1) "2" 
    } 
}

我如何删除完整的数组

["cod"]=> array(3) {     
    ["code"]=> string(3) "cod" 
    ["title"]=> string(38) "Pay on delivery" 
    ["sort_order"]=> string(1) "1" 
    }    

从上面的多维数组创建没有["cod"]数组的新多维数组？谢谢

unset($arr['cod']);是你所需要的全部.文件:http://php.net/manual/en/function.unset.php
