Older PHP version fix
<p>Trying to dynamically load a class:</p>

<pre><code>    require_once(PATH_MODULES."/{$module}/{$module}_admin.php");        
    $admin_class = $module."Admin";     
    return $admin_class::get_admin($module);
</code></pre>

<p>Produces this error on older versions of PHP:</p>

<pre><code>Parse error: syntax error, unexpected
T_PAAMAYIM_NEKUDOTAYIM in 
/home/user/public_html/folder/path/admin/filename.php on line 91 
</code></pre>

<p>How can I change this code to work for older versions of PHP?</p>
