Call to undefined function: ocilogon()

[Anon]

Hi, I have a web site and the people who is providing the hosting service, have just migrated the application and they are receiving this message.
Fatal error: Call to undefined function: ocilogon() in /content/universd/docs/admin/connect.php on line 7

Connect.php has this script
<?

$db=\"pgstage\";
putenv(\"ORACLE_SID=pgstage\");
putenv(\"ORACLE_HOME=/home/oracle\");

$conn=ocilogon(\"universi_user\", \"password\", $db);

?>
They are using oracle 8.1 in the new architecture. Also Apache/1.3.26 (Unix) PHP/4.2.0 mod_perl/1.27.

I\'m 95% sure that since it worked in the previous server, the problem is because this new oracle version. We need to solve this ASAP, any advise???

Best regards.

Well if you are getting undefined function on the ocilogon, that normally means you dont have php compiled with Oracle support. Does your phpinfo() show that you have oracle support?
