Custom Function Calls

+ +

$this->db->call_function();

+ +

This function enables you to call PHP database functions that are not natively included in Code Igniter, 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 Code Igniter. 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; + + + + + + + + + + + + + +
