-<h1>Custom Function Calls</h1>
-
-<h2>$this->db->call_function();</h2>
-
-<p>This function enables you to call PHP database functions that are not natively included in CodeIgniter, in a platform independent manner.
-For example, lets say you want to call the <dfn>mysql_get_client_info()</dfn> function, which is <strong>not</strong> natively supported
-by CodeIgniter. You could do so like this:
-</p>
-
-<code>$this->db->call_function('<var>get_client_info</var>');</code>
-
-<p>You must supply the name of the function, <strong>without</strong> the <var>mysql_</var> 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.</p>
-
-<p>Any parameters needed by the function you are calling will be added to the second parameter.</p>
-
-<code>$this->db->call_function('<var>some_function</var>', $param1, $param2, etc..);</code>
-
-
-<p>Often, you will either need to supply a database connection ID or a database result ID. The connection ID can be accessed using:</p>
-
-<code>$this->db->conn_id;</code>
-
-<p>The result ID can be accessed from within your result object, like this:</p>
-
-<code>$query = $this->db->query("SOME QUERY");<br />
-<br />
-<var>$query->result_id;</var></code>
