A tree directory structure written entirely in PHP

The tree directory looks novel and unique, but most of the ones on the Internet are a combination of JAVASCRIPT and PHP. This one is written entirely in PHP4 and uses the SESSION function. Please give me your comments after reading it. (I passed the test under WIN98/PWS/PHP4)
// 2001/02/23
//ZHANGHEXUN
//Tree directory
session_start(); / /Start a SESSION
if (!session_is_registered("$office_action")){
$office_action=0;
session_register("$office_action");//Register a SESSION
}
if(!session_is_registered("$pho_action")){
$pho_action=0;
session_register("$pho_action");
}
if (!session_is_registered("$web_action")){
$web_action=0;
session_register("$web_action");
}
$office=array('wps','office2000','Peking University Founder'); //Office Star Project
$pho=array('photoshop','3D MAX','fish','Firworks');
$web=array('php','asp','jsp','html' ,'javascript','perl');
