Oracle8i PEAR Connection problem

Hello, mailing-list people, I need help about connect the RDBMS Oracle8i through PEAR library, look this code <html><head><title>Test DB Class - PEAR</title></head> <body> <table border=1> <tr><th>NAME</th><th>PHONE</th><th>ADDRESS</th></tr> <?php //connect require_once('DB.php'); $db =DB::connect("oci8://system:manager@localhost/orcl"); // message if (DB::iserror($db)) { die($db->getMessage()); } //issue the query $sql ="SELECT *

        FROM S_CUSTOMER";

$q =$db->query($sql); // message if (DB::iserror($q)) { die($q->getMessage()); } //generate table while ($q->fetchInto($row)) { ?> <tr><td><?= $row[0] ?></td> <td><?= $row[1] ?></td> <td><?= $row[2] ?></td> </tr> <?php } ?> </table> </body></html> When I execute this code, I receive this output: DB Error: extension not found

 NAME     PHONE     ADDRESS

I think that is a problem with the DSN in the connection (oci8://system:manager@localhost/orcl) I put oci8 for the db type, user: system, pass: manager, and db: orcl I could connect oracle8i with PHP, but using ODBC methods, I want now connect oracle8i through the PEAR library. If someone know, please give me a hand, thanks.
