如何更改日期和时间格式并在html表(php,MYSQL)中打印$ row ['create_date']

http://34.70.95.122/homework/final/messaging.php

我想将其更改为月/日/年。非常感谢

while ($row = mysqli_fetch_assoc($result)) {

    echo "<tr><td class='center'>" . $row['first_name'] . " " . 
         $row['last_name'] . "</td><td class='center'>" . 
         $row['subject'] . "</td><td class='center'>" .
         $row['create_date'] . "</td><td class='center'>" . 
         $row['thread'] . "</td><td><a href='message_view.php?id=" . 
         $row['message_id'] . 
         "' class='link'>view</a></td><td><a href='message_edit.php?id=" . 
         $row['message_id'] . "' class='link'>delete</a></td></tr>";

    }
