将数据动态添加到网格数组

>我有一个数组，问题是我想在数组中添加一些字段，这对于每个保存操作的模型都是通用的。因此，请向我建议适当的解决方案，以使用任何循环将运行时的字段值添加到数组中。我的演示数组是

Array
(
    [submit1] => Submit
    [Customer] => Array
        (
            [Code] => CUS-14-15-016
            [Name] => hggh

                )
            [SuspensionTo] => Array
                (

                    [Phone] => 0
                    [Fax] => 
                )
            [1] => Array
                (

                    [ZipCode] =>

                    [Mobile] => 0
                    [Phone] => 0
                    [Fax] => 
                )
        )

我想添加$create = array（'CreatedBy' => '1'， 'ModifiedBy'=>''， 'CreatedDate'=>date（'Y-m-d'）， 'ModifiedDate'=>date（'Y-m-d'））;此字段值为"客户和联系人地址"数组。
