Can i download the Oracle client libraries on their website?
i think you just have to include the php_oci8.dll and/or the php_oracle.dll in the php.ini depending on the interface you want to use (you can use two sets of functions to access the db: ora_xxx and oci_xxx). the dlls are in your php/extensions directory. you also have to fill in the correct extensions path at extension_dir = "", so the php.exe may find these dlls.
this version of php does support oracle, you just have to switch it on.
good luck.

No you can't. Oracle doesn't provide the client libraries for download. You need to get a copy of Oracle for Linux. one of the trial versions that they have available for download may do the job.

i downloaded the oracle8i enterprise for linux. Is it compatible to Oracle 8 (not i) enterprise edition? co'z thats our serving running on windows nt
Yes the client libraries should be backwards compatible.
You have to install a oracle client. Versions 8.1.6 or 8.1.7 for linux will fit your needs. As you wrote that you use linux I assume that you use apache/php combonation. To get the whole thin working you will have to export the oracle variables
Simply put theese line to your /etc/profile
ORACLE_BASE=/opt/oracle
ORACLE_HOME=/opt/oracle/Or
ORA_NLS33=/opt/oracle/OraH
ORACLE_OWNER=oracle
NLS_LANG=AMERICAN_AMERICA.
TNS_ADMIN=/opt/oracle/OraH
of course replace the paths to fit your installation. don't forget to export the variables. The next thing is you have to
set up your tnsnames.ora and sqlnet.ora located in TNS_ADMIN directory
here is a sample sqlnet.ora file
names.default_domain = WORLD
name.default_zone = WORLD
names.directory_path = (TNSNAMES, HOSTNAME)
and here is a sample tnsnames.ora entry
ORACLE_SID.WORLD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (COMMUNITY = tcp.world)(PROTOCOL = TCP)(Host = 12.2.33.12)(Port = 1521))
(ADDRESS = (COMMUNITY = tcp.world)(PROTOCOL = TCP)(Host = 12.2.33.12)(Port = 1526))
)
(CONNECT_DATA = (SID = ORACLE_SID)(SERVER=DEDICAT
)
to test it try first the tnsping utility tnsping oracle_sid if it returns OK try sqlplus username/password@oracle_s
And one common pitfall: you might get some trouble when starting the apache instance with apachectl script it does not read the enviroment variables. try to start it with the original httpd script. Another solution is to put the variables from /etc/profile to the starting script and also to the apache owners .bash_profile.
To make sure that everything is in place try to write a sample php script
<?
echo getenv("ORACLE_HOME");
echo getenv("TNS_ADMIN");
echo getenv("NLS_LANG");
?>
that's all hope it helps
