将JSON转换为PHP数组

Question

我正在向包含多个项目的PHP发送JSON帖子。 我的JSON看起来像这样：

 [
    {
        "request": "submitTicket",
        "id": "3",
        "delivLoc": "1 COLORADO CITY",
        "estimatedBarrels": "123.0",
        "facilityID": "T666778",
        "highDegreeF": "0.0",
        "highOilFeet": "0"
    },
    {
        "request": "submitTicket",
        "id": "4",
        "delivLoc": "1 COLORADO CITY",
        "estimatedBarrels": "143.0",
        "facilityID": "T666778",
        "highDegreeF": "0.0",
        "highOilFeet": "0"
    },
    {
        "request": "submitTicket",
        "id": "5",
        "delivLoc": "1 COLORADO CITY",
        "estimatedBarrels": "122.0",
        "facilityID": "T666778",
        "highDegreeF": "0.0",
        "highOilFeet": "0"
    }
]

我一直试图在PHP中使用json_decode（），但它返回null，这会导致foreach循环失败。 为什么解码不起作用？

实际上，此JSON在到达PHP时会反斜线放入其中。 在发布到这里之前，我将其取出来，还尝试使用stripslashes（）运行它。

Answer 1

尝试这个..

$data ='[

{"request":"submitTicket","id":"3","delivLoc":"1 COLORADO CITY","estimatedBarrels":"123.0","facilityID":"T666778","highDegreeF":"0.0","highOilFeet":"0"},
{"request":"submitTicket","id":"4","delivLoc":"1 COLORADO CITY","estimatedBarrels":"143.0","facilityID":"T666778","highDegreeF":"0.0","highOilFeet":"0"},
{"request":"submitTicket","id":"5","delivLoc":"1 COLORADO CITY","estimatedBarrels":"122.0","facilityID":"T666778","highDegreeF":"0.0","highOilFeet":"0"}

]';

$jsonarray=json_decode($data,true);
print_r($jsonarray);

我听了每个人的建议后就弄清楚了。 在尝试解码JSON之前，我必须从帖子中删除斜杠。 我这样解码为PHP数组：

$data = json_decode(stripslashes($_POST['json']));

我想昨晚为时已晚，我对此有些疏忽。 感谢大家的帮助和快速的回​​复。

尝试这个。

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

var_dump(json_decode($json));
var_dump(json_decode($json, true));

输出：

 object(stdClass)#1 (5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

array(5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

Answer 4

我看到的是传递的实际数据可能是无效的json。

只需在变量中分配数据并像这样使用

var data = [{
        "request": "submitTicket",
        "id": "3",
        "delivLoc": "1 COLORADO CITY",
        "estimatedBarrels": "123.0",
        "facilityID": "T666778",
        "highDegreeF": "0.0",
        "highOilFeet": "0"
    },
    {
        "request": "submitTicket",
        "id": "4",
        "delivLoc": "1 COLORADO CITY",
        "estimatedBarrels": "143.0",
        "facilityID": "T666778",
        "highDegreeF": "0.0",
        "highOilFeet": "0"
    },
    {
        "request": "submitTicket",
        "id": "5",
        "delivLoc": "1 COLORADO CITY",
        "estimatedBarrels": "122.0",
        "facilityID": "T666778",
        "highDegreeF": "0.0",
        "highOilFeet": "0"
    }
]

然后在数据部分中将其与ajax（我假设您正在使用ajax）一起传递

$.ajax({
    url:[your url],
    data:data,
    ....
});

希望这会工作
