Append Data to JSON File using PHP



How to Append form data to JSON File in PHP Programming Language. I have create one HTML form, I want to add the form data into one json file. For this I have use file_get_contents() and file_put_contents(). File_get_contents() function get json file contents and with the help of php I have convert that content into array formate by using json_decode() function. After this now I want to add form data into this array. For this I have store form data into one array when user submit form, then at that time that form data will store into array. After this I append this form data array into array which I have converted from json file. Now Form data are added into array, so I convert that array into json formate by using json_encode() function. Now all data are converted into json formate, so last I have use file_put_contents() function. With the help of this function I have overwrite this json data on to file.

 <?php  
 $message = '';  
 $error = '';  
 if(isset($_POST["submit"]))  
 {  
      if(empty($_POST["name"]))  
      {  
           $error = "<label class='text-danger'>Enter Name</label>";  
      }  
      else if(empty($_POST["gender"]))  
      {  
           $error = "<label class='text-danger'>Enter Gender</label>";  
      }  
      else if(empty($_POST["designation"]))  
      {  
           $error = "<label class='text-danger'>Enter Designation</label>";  
      }  
      else  
      {  
           if(file_exists('employee_data.json'))  
           {  
                $current_data = file_get_contents('employee_data.json');  
                $array_data = json_decode($current_data, true);  
                $extra = array(  
                     'name'               =>     $_POST['name'],  
                     'gender'          =>     $_POST["gender"],  
                     'designation'     =>     $_POST["designation"]  
                );  
                $array_data[] = $extra;  
                $final_data = json_encode($array_data);  
                if(file_put_contents('employee_data.json', $final_data))  
                {

                }  
           }  
           else
