将json打印到字符串

I have to write json result in a string.

Here is my code,

<!DOCTYPE html> <html lang="en">
     <head>
         <meta charset="UTF-8">
         <title></title>
     </head>
     <body>
         <form method="POST">
             Enter Pin <input type="text" name="pinCode">
             <input type="submit" name="formSubmit">
         </form>
     </body> </html>


 <?php

     if(isset($_POST['formSubmit']))
     {
         $input = $_POST['pinCode'];
         $shortUrl=file_get_contents("https://www.whizapi.com/api/v2/util/uiin/indian-city-by-postal-code?project-app-key=<app_key>&pin=".$input);
         $res = json_decode($shortUrl, true);

         echo implode($res);
     }

 ?>

Currently the outcome is on json format. I have to print the result in string. e.g - { "title" : "Mr", "name" : "sandeep"}. Result would be like "Mr sandeep". That's why I have used json_decode for changing json into array but then I couldn't understand how to change associative array in string.

Thanks in advance.

    Don't decode the json if you want it in string. The output is string and you are converting it to array using json_decode so just comment that line

    if(isset($_POST['formSubmit']))
{
    $input = $_POST['pinCode'];
    $shortUrl=file_get_contents("https://www.whizapi.com/api/v2/util/ui/in/indian-city-by-postal-code?project-app-key=<app_key>&pin=".$input);
    //$res = json_decode($shortUrl, true);

    echo $shortUrl;
}
