[SOLVED] interface help :(

[sasori]

i creadted this test script and saved as interface.dbdriver.php

 

<?php

/**
* @author rmbapc
* @copyright 2008
*/
//interfaced.dbdriver.php
interface DBDriver
{
public function connect();
public function execute($sql);
}
?>

 

and then i created another file and saved as class.mysqldriver.php

<?php

/**
* @author rmbapc
* @copyright 2008
*/
//class.mysqldriver.php
include("interface.dbdriver.php");
class MySQLDriver implements DBDriver
{

}

?>

 

i tried to run the class.mysqldriver.php and the error says

 

Fatal error: Class MySQLDriver contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (DBDriver::connect, DBDriver::execute) in C:\wamp\www\test2\oop\class.mysqldriver.php on line 12

 

now my question is, "why does the error says, 2 abstract methods?" when infact i made an interface and not an abstract right?

In order for an interface to work, you must provide an implementation of every method in the interface in any class that implements it. >_>  Basically MySQL driver NEEDS a connect() and execute($sql) method of equal or greater visibility.
