PHP return inside object

Question

I'm wondering why I can't return result with getData() function? it is empty in browser (PHP 7.1), I'm trying to understand why.

I can print/echo it just fine o.O

class testObject
{
     public $data;

     function __construct($data) 
     {
         $this->data = $data;

     }

     function showInfo() 
     {
         print_r($this->data);
     }


     function getData() 
     {
         $str = $this->data;
         return $str;
     }
}
$data = 'test';
$a = (new testObject($data))->getData();

You're doing something wrong because this is working fine: ideone.com/5V3Fgz — Phiter

Before $a You must write echo or print, because your method returns data, but you must tell what this data should be shown.

This works fine for me just running it in PHP Sandbox.

If you want to show it in the browser, put a echo or print after the $a.
