OCILOGON错误ORA 12514

Question

I am getting

Array (
       [code] => 12514     
       [message] => Error while trying to retrieve text for error ORA-12514     
       [offset] => 0     
       [sqltext] =>  
    )

when calling the Ocilogon function to connect with oracle. I got the correct string but still getting the error.

ocilogon() is deprecated (along with many other aliases ) and you should not be using it in new code. Use oci_connect() instead.

Personally I use the following code that doesn't rely on environment settings like TNS_ADMIN :

oci_connect($username, $password, $conn_string);

Where $conn_string is a valid connection string that looks something like this:

(DESCRIPTION =
    (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = HOST.EXAMPLE.COM)(PORT = 1521))
    )
    (CONNECT_DATA = (SID = EXAMPLE))
)

You can copy the connection string directly from your TNSNAMES.ORA file.
