如何在PHP中以原始形式从POSTMAN application / json接收多个值“Array”(How to receive multiple values “Array” from POSTMAN application/json in raw form in PHP)

 当我尝试在PHP中接收多个数组值进行验证时，我遇到了一些问题。 我有这个对象与POSTMAN原始形式， application/json ： 
 
{
  "name":"create_insert_new_delivery",
  "param":{
       "email_of_shipment_owner":"hi@example.com",
       "shipment_type ":"B",
       "item_name": ["50", "60"],
       "item_weight ": ["H", "I"],
       "item_length": ["70", "90"]
 }
}
 
 当我尝试接收$ item_name = $ this-> validateParameter（'item_name'，$ this-> param ['item_name']，ARRAY，true）; 就像收到下面的两个字符串一样，我得到了这个 
 
 **错误：** 
 
 
 
 [04-Jul-2018 13:16:58 UTC] PHP Parse错误：语法错误，意外'，'，期待'（'在/home/osconliz/public_html/Osconlizapicall/api.php第304行 
 
 
 接收代码如下。 
 
 LINE 302 
 
$email_of_shipment_owner = $this->validateParameter('email_of_shipment_owner', $this->param['email_of_shipment_owner'], STRING, true);
 
 LINE 303 
 
 $shipment_type = $this->validateParameter('shipment_type', $this->param['shipment_type'], STRING, true);
 
 LINE 304 
 
$item_name = $this->validateParameter('item_name', $this->param['item_name'], ARRAY, true);
 
 LINE 305 
 
 $item_weight = $this->validateParameter('item_weight', $this->param['item_weight'], ARRAY, true);
 
 LINE 306 
 
$item_length = $this->validateParameter('item_length', $this->param['item_length'], ARRAY, true);
 
 但STRINGS正确收到： 
 
public function validateParameter($fieldName, $value, $dataType, $required = true){
        switch ($dataType) {
            case BOOLEAN:
            if (!is_bool($value)){
                $this->throwError(VALIDATE_PARAMETER_DATATYPE, "Datatype is not valid for " . $fieldName . ' it should be boolean.');
            }
            break;
            case INTEGER:
            if (!is_numeric($value)){
                $this->throwError(VALIDATE_PARAMETER_DATATYPE, "Datatype is not valid for " . $fieldName . ' it should be integer.');
            }
            break;
            case STRING:
            if (!is_string($value)){
                $this->throwError(VALIDATE_PARAMETER_DATATYPE, "Datatype is not valid for " . $fieldName . ' it should be string.');
            }
            break;
            case ARRAY:
            if (!is_array($value)){
                $this->throwError(VALIDATE_PARAMETER_DATATYPE, "Datatype is not valid for " . $fieldName . ' it should be array.');
            }
            break;

            default:
            $this->throwError(VALIDATE_PARAMETER_DATATYPE, "Datatype is not valid for " . $fieldName);
            break;

        }

        return $value;
  }
 
 收到后我想验证这样的数据 
 
    if ($this->item_category == ""){

          } else {


          if ($this->item_category == "A" || $this->item_category == "B" || $this->item_category == "C" || $this->item_category == "D" || $this->item_category == "E" || $this->item_category == "F" || $this->item_category == "G" || $this->item_category == "H") {

          } else {
            $this->throwError(INVALID_DATA_TTT, "Invalid item category");
           exit();  
          }
          } 

I am having a little issue when I try to receive multiple array values in PHP for validation. I have this object with values in POSTMAN raw form, application/json :
 
{
  "name":"create_insert_new_delivery",
  "param":{
       "email_of_shipment_owner":"hi@example.com",
       "shipment_type ":"B",
       "item_name": ["50", "60"],
       "item_weight ": ["H", "I"],
       "item_length": ["70", "90"]
 }
}
 
When I try to receive $item_name = $this->validateParameter('item_name', $this->param['item_name'], ARRAY, true); like the two strings below are received I get this 
 
**ERROR : **
 
 
 
[04-Jul-2018 13:16:58 UTC] PHP Parse error: syntax error, unexpected ',', expecting '(' in /home/osconliz/public_html/Osconlizapicall/api.php on line 304
 
 
The receiving code below.
 
LINE 302 
 
$email_of_shipment_owner = $this->validateParameter('email_of_shipment_owner', $this->param['email_of_shipment_owner'], STRING, true);
 
LINE 303 
 
 $shipment_type = $this->validateParameter('shipment_type', $this->param['shipment_type'], STRING, true);
 
LINE 304 
 
$item_name = $this->validateParameter('item_name', $this->param['item_name'], ARRAY, true);
 
LINE 305 
 
 $item_weight = $this->validateParameter('item_weight', $this->param['item_weight'], ARRAY, true);
 
LINE 306 
 
$item_length = $this->validateParameter('item_length', $this->param['item_length'], ARRAY, true);
 
but the STRINGS are received properly : 
 
public function validateParameter($fieldName, $value, $dataType, $required = true){
        switch ($dataType) {
            case BOOLEAN:
            if (!is_bool($value)){
                $this->throwError(VALIDATE_PARAMETER_DATATYPE, "Datatype is not valid for " . $fieldName . ' it should be boolean.');
            }
            break;
            case INTEGER:
            if (!is_numeric($value)){
                $this->throwError(VALIDATE_PARAMETER_DATATYPE, "Datatype is not valid for " . $fieldName . ' it should be integer.');
            }
            break;
            case STRING:
            if (!is_string($value)){
                $this->throwError(VALIDATE_PARAMETER_DATATYPE, "Datatype is not valid for " . $fieldName . ' it should be string.');
            }
            break;
            case ARRAY:
            if (!is_array($value)){
                $this->throwError(VALIDATE_PARAMETER_DATATYPE, "Datatype is not valid for " . $fieldName . ' it should be array.');
            }
            break;

            default:
            $this->throwError(VALIDATE_PARAMETER_DATATYPE, "Datatype is not valid for " . $fieldName);
            break;

        }

        return $value;
  }
 
After receiving I want validate data like this
 
    if ($this->item_category == ""){

          } else {


          if ($this->item_category == "A" || $this->item_category == "B" || $this->item_category == "C" || $this->item_category == "D" || $this->item_category == "E" || $this->item_category == "F" || $this->item_category == "G" || $this->item_category == "H") {

          } else {
            $this->throwError(INVALID_DATA_TTT, "Invalid item category");
           exit();  
          }
          }
