How to get User's Username from ID?

Question

This is the part of the code

<td>
        <span class="info_label">
        <?php echo JText::_( "JFORMS_FIELD_CREATED_BY_USERNAME" ); ?>
        </span>:<br />
        <?php echo $this->item->created_by; ?>
    </td>

It obviously return user ID who submitted the form . How can I get username instead? Thanks

I'm not sure if this is for a custom component or a core Joomla component, but to get the author's name, you can simply use the following:

<?php echo $this->item->author; ?>

If the component has the option to select an alias for the author, then you should use this instead:

<?php 
    $author = ($this->item->created_by_alias) ? $this->item->created_by_alias : $this->item->author; 
    echo $author;
?>

Update:

<?php
    echo JFactory::getUser($this->item->created_by)->get('username');
?>
