Custom Function Calls

- -

$this->db->call_function();

- -

This function enables you to call PHP database functions that are not natively included in CodeIgniter, in a platform independent manner. -For example, lets say you want to call the mysql_get_client_info() function, which is not natively supported -by CodeIgniter. You could do so like this: -

- -$this->db->call_function('get_client_info'); - -

You must supply the name of the function, without the mysql_ prefix, in the first parameter. The prefix is added -automatically based on which database driver is currently being used. This permits you to run the same function on different database platforms. -Obviously not all function calls are identical between platforms, so there are limits to how useful this function can be in terms of portability.

- -

Any parameters needed by the function you are calling will be added to the second parameter.

- -$this->db->call_function('some_function', $param1, $param2, etc..); - - -

Often, you will either need to supply a database connection ID or a database result ID. The connection ID can be accessed using:

- -$this->db->conn_id; - -

The result ID can be accessed from within your result object, like this:

- -

$query = $this->db->query("SOME QUERY");

-

-$query->result_id;
