如何修改mongo数组中指定数组里的值
mongo数组如下：array (
'_id' => new MongoId("5281d8fa942a88200e000000"),
'uid' => new MongoInt32(3000001),
'cardsBag' =>
array (
'0' =>
array (
'id' => new MongoInt32(3),
'count' => new MongoInt32(1),
'fightIndex' => new MongoInt32(6),
'property' =>
array (
'0' => new MongoInt32(99),
'1' => new MongoInt32(321),
),
),
'1' =>
array (
'id' => new MongoInt32(110),
'count' => new MongoInt32(1),
'fightIndex' => new MongoInt32(1),
'property' =>
array (
'0' => new MongoInt32(99),
'1' => new MongoInt32(123),
),
),
'2' =>
array (
'id' => new MongoInt32(98),
'count' => new MongoInt32(1),
'fightIndex' => new MongoInt32(-1),
'property' =>
array (
'0' => new MongoInt32(99),
'1' => new MongoInt32(234),
),
),
'3' =>
array (
'id' => new MongoInt32(96),
'count' => new MongoInt32(1),
'fightIndex' => new MongoInt32(0),
'property' =>
array (
'0' => new MongoInt32(99),
'1' => new MongoInt32(432),
),
),
),)
我想更改这个数组里的cardsBag里的第二个数组里面的值。update 要怎么写呢？
