使用 PHP 连接到 Oracle DB

Question

I'm trying to connect to an Oracle database using PHP using the following code:

$username = 'my_username';
$password = 'my_password';
$environment = 'my_environment';
// CHANGE HOST, PORT, SID
$tns = "
(DESCRIPTION =
     (ADDRESS_LIST =
          (ADDRESS = (PROTOCOL = TCP)(HOST = my_host)(PORT = my_port))
     )
     (CONNECT_DATA =
          (SID = my_sid)
     )
)
";

$conn = oci_connect($username, $password, $tns);

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

It is working fine. But what I want to do is connect without exposing the username and password in plain text. Like in Postman where you can use Basic authentication header instead of plain text. Is there a way to do that?

Answer 1

The preferred solution is to use an Oracle wallet, doing "External Authentication". See p116 of Oracle's free The Underground PHP and Oracle Manual .

Once the wallet is set up your code would look like:

$c = oci_connect("/", "", $tns, null, OCI_CRED_EXT);

An lesser alternative is to pass the password in from an environment variable.
