使用PHP从Oracle获取数据

Question

I'm trying to develop website using php but I have two servers:

*one for php files

*other one for database (oracle)

so I'm trying to get data from database using following connection string

$dbstr=
  (DESCRIPTION=
    (ADDRESS=
      (PROTOCOL=TCP)
      (HOST=xxx.xx.x.xx)
      (PORT=1521)
    )
    (CONNECT_DATA=
      (SERVER=dedicated)
      (SERVICE_NAME=BHDB)
    )
  )
    global $objConnect;
    $objConnect = oci_connect('building', 'building', $dbstr, 'AL32UTF8');
if (!$objConnect) {
            $e = oci_error();
            trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
        }

but in oci_connect the file can't display any thing in php (blank page)

but I don't know the problem

Answer 1

Add

error_reporting(E_ALL);  // In PHP 5.3 use E_ALL|E_STRICT
ini_set('display_errors', 'On');

to your script and check the errors.

You can simplify your connection string to:

$dbstr='xxx.xx.x.xx/BHDB';

I get the impression you haven't read the Underground PHP & Oracle Manual .
