Connecting to Oracle with PHP

[Mingas]

Guys please help. I have been tasked to create a php page that would connect to an Oracle DB given the below:

Table name that is holding the Solutions info is called: REMMIS2.PBM_SOLUTION_DATABASE

Please see below the TNS connection string.
User id = myid
Password = mypass

REMPRD02=
(DESCRIPTION =
(FAILOVER = ON)
(LOAD_BALANCE = ON)
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.182.237.53)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.182.237.53)(PORT = 1522))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.182.237.53)(PORT = 1721))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.182.237.53)(PORT = 1722))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.182.237.54)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.182.237.54)(PORT = 1522))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.182.237.54)(PORT = 1721))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.182.237.54)(PORT = 1722))
(CONNECT_DATA =
(SERVICE_NAME = MISPRDS1)
(FAILOVER_MODE =
(TYPE = session)
(METHOD = basic)
(DELAY = 5)
(RETRIES = 100)
)
)
)


What I have tried is :

<?php
// Create connection to Oracle
$conn = oci_connect("myid", "mypass", "10.182.237.53/MISPRDS1");
if (!$conn) {
$m = oci_error();
echo $m['message'], "\n";
exit;
}
else {
print "Connected to Oracle!";
}
// Close the Oracle connection
oci_close($conn);
?>

But I cannot establish a connection. I'm not sure if i would first need download instantclient package from Oracle for my server that is running PHP or if my code is wrong. Please assist
