How do I insert an alt="something-here" attribute into PHP code?
<p>I have a semi-transparent icon located in the bottom-right of my screen.  It's obvious; it's an arrow pointing up, implying that the user can scroll to the top if the page or post is too long.</p>

<p>But I'd like it to have an <strong>alt="Scroll to top"</strong> attribute when the user hovers over the icon for a few reasons.  How can I achieve this?  The PHP code where the link is looks like this:</p>

<pre><code>  public function plugin_action_links( $action_links )
  {
     array_unshift( $action_links, "&lt;a href=\"" . STT_OPTIONS_URL . "\"&gt;" . __( 
   'Settings', 'scrollto-top' ) . "&lt;/a&gt;" );

     return $action_links;
  }
</code></pre>

<p>If more information is needed, please let me know.  I've tried things, but they always break the code.  I'm sure I have to put something in the &lt; a href part of this code, but I'm unsure as to the syntax I'd use, or where I'd use it.  Any help would be greatly appreciated!</p>
