OCILOGON function not recognozed by PHP4

i recently installed apache and php4 on my RH 6.2 box. i then installed oracle8i (8.1.6) on it and successfully setup the db. so far so good. i then recompiled php4 with the --with-oci8 switch successfully without any errors. i executed a phpinfo() script to see the new oracle variables ... i can see them under "PHP Variables" and "Additional Modules" sections. but when i run a simple script using the ocilogon() function, i get the error ... "Fatal error: Call to undefined function: ocilogon() in /usr/local/apache/htdocs/oratest.php on line 3" my php script is as under .... <?php print "<HTML><BODY>"; $c1 = ocilogon("scott","tiger"); function select_data($conn) { $stmt = ociparse($conn,"select * from emp"); ociexecute($stmt); echo $conn."----selecting\n\n"; while (ocifetch($stmt)) echo $conn." <".ociresult($stmt,"TEST").">\n\n"; echo $conn."----done\n\n"; } select_data($c1); print "</BODY></HTML>"; ?> where am i going wrong? why cant PHP execute my ocilogon() function? urgent help needed plz. -- kannan, mumbai, india
