它是一个完美的JSON字符串。

(&P； 这是我的代码，

$("#button").click(function(e)

{

    data = {};
    $(document).find('[name]').each(function(index , value)
    {
    name = $(this).attr('name'),
    value = $(this).val();
    data[name] = value;
    });
    dataString = JSON.stringify(data);
    //console.log(dataString);
    $.ajax({
    url : "empcontact.php",
    type : "post",
    data : dataString, 
    success : function (response) {
    console.log(response);
    }
    })
    return false;
    });

    $requestpayload =  file_get_contents("php://input");
        $array = json_decode($requestpayload , true);
    
            foreach($array as $row)
            {   
                $name = $row['txtname'];
                $gender = $row['txtgender'];
                $designation = $row['txtdesignation'];
    
                $sql = "INSERT INTO tbl_employee (Name, Gender, Designation) VALUES ('$name' , '$gender' , '$designation')";
                
                mysqli_query($connect, $sql);
            }
        
            
            echo "Employee data submitted successfully";
