Question

这是mongo文档。我需要使用相关令牌提取所有数据的代码。

{
"_id": {
    "$oid": "59cfb47b78a26d86cc5fdd7a"
},
"event": "Coding",
"data": [
    {
        "first_name": "Chanchal",
        "last_name": "Roshan",
        "email": "chan@gmail.com",
        "phone": "75044",
        "college": "AIT",
        "members": "1",
        "amount": "25",
        "branch": "IT",
        "token": "684695669",
        "event": "Coding"
    },
    {
        "first_name": "Ravi",
        "last_name": "Raj",
        "email": "i@gmail.com",
        "phone": "89746",
        "college": "AIT",
        "members": "1",
        "amount": "250",
        "branch": "IT",
        "token": "128027522",
        "event": "Coding"
    }
],
"auth_token": "z1iZ0LnDHFhs48PlYjNHyCjeh7y1"

}

我是php新手，对不起这些基本问题。

我假设您的意思是给定令牌XXX，找到data数组的元素包含token="XXX"的所有文档，并返回该数组的元素，而不是整个数组。这应该工作。注意data.token以及在投影（arg 2）中使用$位置运算符：

db.foo.find({"data.token":"XXX"},{"data.$":1});

我怎么能用密钥作为令牌在php中查询mongodb？
