Php Oracle connection: oci_connect(): ORA-24315: illegal attribute type error

Question

I am trying to connect to Oracle database using php in windows.

$db = "BLM = (DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = host)(PORT = 1521))
(CONNECT_DATA =
  (SERVER = DEDICATED)
  (SERVICE_NAME = blm)
)
)";
$conn = oci_connect('blmuser', 'blmuser', $db);

if (!$conn) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
} 

I am getting the error oci_connect(): ORA-24315: illegal attribute type

I have tried setting the instant client path but to no avail.

phpinfo()

Answer 1

Solved the issue. I was trying with only php_oci8_11g.dll enabled in php.ini. Enabled php_oci8.dll extension and everything is working fine.

Just remove the BLM= as you need to give the description only as connection identifier. The former is needed, when you want to refer the alias name (BLM) as in tnsnames.ora instead of the full description.

$db = "(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = host)(PORT = 1521))
(CONNECT_DATA =
  (SERVER = DEDICATED)
  (SERVICE_NAME = blm)
)
)";

Answer 3

Notice how the marked extensions are ordered:

You should have extension=php_oci8.dll and then extension=php_oci8_11g.dll :
