I cannot give you a direct solution. By that I mean sample code.
Why? Because there are too many ways and too many possible locations to set up.
$ORACLE_HOME/bin/tnsping tells you if a given listener is up - the listener being the one for that given ORACLE_HOME [9i or 10g]. You must execute this on a box that is not the same as the db server zone or server. Example: your desktop PC with Oracle client installed, or an application Solaris zone that has Oracle client installed.
Set your environment to either 10g or 9i by directing ORACLE_HOME to the correct value, then
execute in a script or from the command line:
Note that db's of a given version, like Oracle 9i, share one listener.

oci_pconnect
OCI_PCONNECT(3)OCI_PCONNECT(3)oci_pconnect - Connect to an Oracle database using a persistent connectionSYNOPSIS
resource oci_pconnect (string $username, string $password, [string $connection_string], [string $character_set], [int $session_mode])
DESCRIPTION
Creates a persistent connection to an Oracle server and logs on.
Persistent connections are cached and re-used between requests, resulting in reduced overhead on each page load; a typical PHP application
will have a single persistent connection open against an Oracle server per Apache child process (or PHP FastCGI/CGI process). See the Per-
sistent Database Connections section for more information.
PARAMETERS
o $username
- The Oracle user name.
o $password
- The password for $username.
o $connection_string
-Contains the Oracle instance to connect to. It can be an Easy Connect string, or a Connect Name from the tnsnames.ora file, or
the name of a local Oracle instance. If not specified, PHP uses environment variables such as TWO_TASK (on Linux) or LOCAL (on
Windows) and ORACLE_SID to determine the Oracle instance to connect to. To use the Easy Connect naming method, PHP must be linked
with Oracle 10 g or greater Client libraries. The Easy Connect string for Oracle 10 g is of the form: [//]host_name[:port][/ser-
vice_name]. From Oracle 11 g, the syntax is: [//]host_name[:port][/service_name][:server_type][/instance_name]. Service names can
be found by running the Oracle utility lsnrctl status on the database server machine. The tnsnames.ora file can be in the Oracle
Net search path, which includes $ORACLE_HOME/network/admin and /etc. Alternatively set TNS_ADMIN so that $TNS_ADMIN/tnsnames.ora
is read. Make sure the web daemon has read access to the file.
o $character_set
-Determines the character set used by the Oracle Client libraries. The character set does not need to match the character set used
by the database. If it doesn't match, Oracle will do its best to convert data to and from the database character set. Depending on
the character sets this may not give usable results. Conversion also adds some time overhead. If not specified, the Oracle Client
libraries determine a character set from the NLS_LANG environment variable. Passing this parameter can reduce the time taken to
connect.
o $session_mode
-This parameter is available since version PHP 5 (PECL OCI8 1.1) and accepts the following values: OCI_DEFAULT, OCI_SYSOPER and
OCI_SYSDBA. If either OCI_SYSOPER or OCI_SYSDBA were specified, this function will try to establish privileged connection using
external credentials. Privileged connections are disabled by default. To enable them you need to set oci8.privileged_connect to
On. PHP 5.3 (PECL OCI8 1.3.4) introduced the OCI_CRED_EXT mode value. This tells Oracle to use External or OS authentication,
which must be configured in the database. The OCI_CRED_EXT flag can only be used with username of "/" and a empty password.
oci8.privileged_connect may be On or Off. OCI_CRED_EXT may be combined with the OCI_SYSOPER or OCI_SYSDBA modes. OCI_CRED_EXT is
not supported on Windows for security reasons.
RETURN VALUES
Returns a connection identifier or FALSE on error.
EXAMPLES
Example #1
Basic oci_pconnect(3) Example using Easy Connect syntax
<?php
// Connects to the XE service (i.e. database) on the "localhost" machine
$conn = oci_pconnect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$stid = oci_parse($conn, 'SELECT * FROM employees');
oci_execute($stid);
echo "<table border='1'>
";
while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) {
echo "<tr>
";
foreach ($row as $item) {
echo " <td>" . ($item !== null ? htmlentities($item, ENT_QUOTES) : " ") . "</td>
";
}
echo "</tr>
";
}
echo "</table>
";
?>
See oci_connect(3) for further examples of parameter usage.
NOTES
Note
Starting with PHP 5.1.2 and PECL OCI8 1.1, the lifetime and maximum number of persistent Oracle connections per PHP process can be
tuned by setting the following configuration values: oci8.persistent_timeout, oci8.ping_interval and oci8.max_persistent.
