Example #2 Basic oci_connect() using Easy Connect syntax
<?php
// Connects to the XE service (i.e. database) on the "localhost" machine
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {

echo " <td>" . ($item !== null ? htmlentities($item, ENT_QUOTES) : " ") . "</td>\n";
}
echo "</tr>\n";
}
echo "</table>\n";
?>
Example #3 Basic oci_connect() using a Network Connect name
<?php
// Connects to the MYDB database described in tnsnames.ora file,
// One example tnsnames.ora entry for MYDB could be:
// MYDB =
// (DESCRIPTION =
// (ADDRESS = (PROTOCOL = TCP)(HOST = mymachine.oracle.com)(PORT = 1521))
// (CONNECT_DATA =
// (SERVER = DEDICATED)
// (SERVICE_NAME = XE)

echo " <td>" . ($item !== null ? htmlentities($item, ENT_QUOTES) : " ") . "</td>\n";
}
echo "</tr>\n";

echo "</table>\n";

Example #4 oci_connect() with an explicit character set
<?php
$conn = oci_connect('hr', 'welcome', 'localhost/XE', 'AL32UTF8');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
