$getId = $_GET['id'];
$User = "scott";

$db = " (DESCRIPTION =\n";
$db .= "(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.111.3)(PORT = 1521))\n";
$db .= "(CONNECT_DATA = (SID = XE))\n";
$db .= ")\n";
$conn = ocilogon($User,$Password,$db);
$sql = "select signature from approvers where empid='0481'";
$stmt = OCIParse($conn,$sql);
if (!OCIExecute($stmt)) { print "execution failed"; exit(); }
OCIFetchInto($stmt, &$arr,OCI_RETURN_LOBS);
// Also tried with OCI_ASSOC
echo ($arr[0]);
?>
in AdoDB
<?php
header ('content-type: image/JPEG');
ini_set ('display_errors', 1);
error_reporting(E_ALL);
$getId = $_GET['id'];
include_once ('adodb.inc.php');
include_once ('adodb-exceptions.inc.php');
include_once ($_SERVER['DOCUMENT_ROOT'].'/conf/inc/conf-era.inc.php');
ini_set ('sendmail_from', MAIL_LOG);
ini_set ('error_log', ERR_PATH);
try
     $dsn = 'oci8://'.DB_USERNAME.':'.DB_PASSWORD.'@'.DB_SERVER.'/'.DB_SID;
     $db_Conn = ADONewConnection($dsn);
     $db_Conn->debug = 1;
     $arr = $db_Conn->GetOne("SELECT Signature FROM Approvers WHERE EmpId=:v_EmpId", array('v_EmpId' => $getId));
     #echo ($arr->fields[0]);
     echo ($arr);
catch (Exception $e)
     echo $e->getMessage();
?>
