Question

我有以下JSON：

{

"thirdPartyForms": [
    {
        "driverAddress": "Adress",
        "PolicyOwner": "nimo",
        "driverInsCompany": "lkjlkj",
        "driverName": "drvivcer name",
        "agentPhone": "kj",
        "carLicensing": "lkjkl",
        "driverId": "0980980980",
        "driverPhone": "098908098",
        "agentName": "j"
    },
    {
        "driverAddress": "",
        "PolicyOwner": "",
        "driverInsCompany": "",
        "driverName": "driver 5",
        "agentPhone": "",
        "carLicensing": "",
        "driverId": "",
        "driverPhone": "",
        "agentName": ""
    }
],
"personalForm": {
    "insDriverName": "",
    "insCarLicensing": "",
    "insId": "039956974",
    "insName": "bnrus",
    "insDriverId": "",
    "insPhone": ""
}
}

我尝试使用我写的这个函数保存所有字段：

    function JSONForm()
    {
        if(get_magic_quotes_gpc()){
            $d = stripslashes($_POST['formJSON']);
        }else{
            $d = $_POST['formJSON'];
        }
        $d = json_decode($d,true);

    $myArray = array();

    foreach($d as $item)
    {

        foreach($item as $key => $value)
        {
            $myArray[$key] = $value."\n";
        }
    }

 }

我没有得到所有的字段（我得到'数组'而不是字段）。这是我的输出：

0 => Array
1 => Array
insDriverName => 
insCarLicensing => 
insId => 039956974
insName => bnrus
insDriverId => 
insPhone =>

如何改进我的功能以使其有效？这意味着 - ＆gt;我无法保存JSONArray中的所有值（输出行1和2）。

解决方案

为了清晰起见，移到了顶部。

尝试以递归方式展平数组

$d = json_decode($json, true);

$it = new RecursiveIteratorIterator(new RecursiveArrayIterator($d));
foreach($it as $k => $v) {
  echo $k . " is " . $v . "\n";
}

原始回答

您的代码按预期工作，您不能echo或print数组，数据就在那里。而是这样做;

function JSONForm()
{
   if(get_magic_quotes_gpc()){
       $d = stripslashes($_POST['formJSON']);
   }else{
       $d = $_POST['formJSON'];
   }
   $d = json_decode($d,true);

   // A var_dump here will show you the true values of all of the
   // decoded array
   var_dump($d);

   // In fact you do not need to iterate over the array, at all
   // because the variable $d already contains all the json data

   $myArray = array();

   foreach($d as $item)
   {
    foreach($item as $key => $value)
    {
        // This will output all the array using print_r, setting the 2nd
        // parameter to be true will return the output, rather than print it
        $myArray[$key] = print_r($value, true)."\n";
    }
   }
 }

修改

这是您的数据;

// thirdPartyForms is an array, it has no keys so the array will be // zero indexed "thirdPartyForms": [ { // this is position zero "driverAddress": "Adress", "PolicyOwner": "nimo", "driverInsCompany": "lkjlkj", "driverName": "drvivcer name", "agentPhone": "kj", "carLicensing": "lkjkl", "driverId": "0980980980", "driverPhone": "098908098", "agentName": "j" }, { // this is position one "driverAddress": "", "PolicyOwner": "", "driverInsCompany": "", "driverName": "driver 5", "agentPhone": "", "carLicensing": "", "driverId": "", "driverPhone": "", "agentName": "" } ], "personalForm": { "insDriverName": "", "insCarLicensing": "", "insId": "039956974", "insName": "bnrus", "insDriverId": "", "insPhone": "" }

然后，您可以使用编号索引访问数组;

// This will give you 'Adress' echo $d["thirdPartyForms"][0]["driverAddress"] // This will give you 'bnrus' echo $d["personalForm"]["insName"];

使用var_dump($d)可以让您更轻松，因为您可以更清楚地看到阵列的组成。

使用循环;

foreach($d as $key => $data) { // This will output the data for a key, note that var_dump will // output an array just fine var_dump($data); // The issue you have is that $data could be a string or another array, // Because your first element "thirdPartyForms" is an array of arrays // The second element "personalForm" is an array of strings // Check if its an array and if so iterate again if(is_array($data)) { echo $key . " is an array\n"; // Here we loop over the array again, note that if you have arrays in a // array then you will need a recursive function foreach($data as $k => $value) { echo $k . " within an array is " . $value . "\n"; } } else { echo $key . " is not an array, it is " . $data . "\n"; } }
