有人知道如何在PHP中循环使用此JSON数组吗？我只是尝试过，但是没有用

[{
   //
    "data": [{
            "id": "1",
            "name": "Tiger Nixon",
            "position": "System Architect",
            "salary": "$320,800",
            "start_date": "2011/04/25",
            "office": "Edinburgh",
            "extn": "5421"
        },
        {
            "id": "2",
            "name": "Garrett Winters",
            "position": "Accountant",
            "salary": "$170,750",
            "start_date": "2011/07/25",
            "office": "Tokyo",
            "extn": "8422"
        },
        {
            "id": "3",
            "name": "Ashton Cox",
            "position": "Junior Technical Author",
            "salary": "$86,000",
            "start_date": "2009/01/12",
            "office": "San Francisco",
            "extn": "1562"
        },
        {
            "id": "4",
            "name": "Cedric Kelly",
            "position": "Senior Javascript Developer",
            "salary": "$433,060",
            "start_date": "2012/03/29",
            "office": "Edinburgh",
            "extn": "6224"
        }
    ]
}]

Answer 1

您应将json转换为数组，然后将每个json对象转换为数组

$json = "current Json data";
$json = json_decode($json); //convert json to array
$json = $json[0]->data; //get all data

foreach ($json as $key => $value) {
    $value = get_object_vars($value); // convert object to array
    print_r($value)
}

Answer 2

首先，将您的JSON解码为PHP数组，然后您可以照常遍历它。

$arrayItems = json_decode($jsonString)

foreach ($arrayItems as $item){
 // do something
}

Answer 3

您可以使用以下代码来迭代json格式：

$jsonData = json_decode($data);
        foreach($jsonData as $jsonDataKey => $jsonDataValue){
            foreach($jsonDataValue as $jsonArrayKey => $jsonArrayValue){
                echo $jsonArrayValue['id'];
                echo $jsonArrayValue['name'];
                echo $jsonArrayValue['position'];
            }
        }
