PHP：搜索并删除JSON对象

Question

I have a quite nested JSON file. How can I delete an array that includes my value? For ex: I want to delete {"customer":"Customer1","date":"2017-06-03"...} from JSON file and I already knew the "Customer1"

{
            "info": [{
                "customer": "Customer1",
                "date": "2017-06-03",
                "beacons": [{
                    "data1": "1234",
                    "data2": "Test1",
                }, {
                    "data1": "0088",
                    "data2": "Test2",
                }]
            },{
                "customer": "Customer2",
                "date": "2017-06-03",
                "beacons": [{
                    "data1": "dcdd4",
                    "data2": "Test3",
                }, {
                    "data1": "0088",
                    "data2": "Test4",
                }]
            }]
        }

Thanks!

There is some issue in your json data. This is not valid json data; I have decoded the josn data & then check if "customer" value = 'Customer1', then remove the array from main array.

It should be like this:

$jsonData = '{"info ": [{
    "customer ": "customer1 ",
    "date ": "2017 - 06 - 03 ",
    "beacons ": [{
        "data1 ": "1234",
        "data2 ": "Test1"
    }]
}, {
    "customer": "customer2 ",
    "date": "2017 - 06 - 04 ",
    "beacons": [{
        "data1": "dcdd4",
        "data2": "Test3"
    }]
 }]
}';

$myData = json_decode($jsonData,true);


foreach($myData["info"] as $k=>$arr) {
    if($arr["customer"] == "customer1") {
       unset($myData["info"][$k]);
    }
}
