现在我想添加一个新的名为键值对 [计数] =＆GT; '$ SOME_VALUE在这个阵列中的每个元素的键值对 [test_pack_purchase_date] （例如在 [test_pack_purchase_date后] =方式＆gt;？255 我应该怎样做这个谁能帮助我在这方面预先感谢
Now I want to add a new key-value pair named [count] => '$some_value' in this array in every element after the key-value pair [test_pack_purchase_date](say after [test_pack_purchase_date] => 255. How should I do this? Can anyone help me in this regard? Thanks in advance.
推荐答案
如果您正在创建新的数组，那么试试这个：
If you are creating new array then try this :
$ ARR =阵列（钥匙=＆gt;中值）;
如果已经创建数组，那么试试这个：
And if array is already created then try this :
$改编[钥匙] =值;
