compiling php with oci8 support

[Joni Lahtinen <lahtinenjk@suomi24.fi>]

Debian sarge

I have oracle XE installed (works with java jdbc)

I downloaded php4 source.

#./configure "--with-oci8=$ORACLE_HOME"
all went right
#make
all ok
#make install
all ok
#../apache2 restart

then php:

<?
$c = OCILogon('hr', 'hr_password', '//mymachine.mydomain/MYDB');
?>

error from php-site:

Fatal error: Call to undefined function: ocilogon() in 
/var/www/web/oracletest.php on line 2

What I do wrong and how to fix it?
