Cannot Get Date format from input field

You really should read up on the DateTime Class etc; On PHP.NET

Here is one example that will help you to check the datetime.

date_parse

Now I am getting below error. 

"Array to string conversion"

This is my code. 

PHP Code:

value="<?php
                                $j_date = date_parse($row->join_date);
                                echo $j_date;   ?> "
