"superglobal object"
<p>Using the following as an example (with $db being a previously created database connection object)...</p>

<pre><code>Class Session {
   function write_log () {
     global $db;
     $db-&gt;query(...);
   }
}
</code></pre>

<p>Is there a way to avoid having to write "global $db" everytime I want to use the $db object inside of another class?  In other words, declare the $db object as a superglobal from the very beginning.</p>
