interfaces support multiple inheritance
<?php
interface SQL_Result extends SeekableIterator, Countable
{
// new stuff
}
abstract class SQL_Result_Common
{
// just because that's what one would do in reality, generic implementation
}
class SQL_Result_mysql extends SQL_Result_Common implements SQL_Result
{
// actual implementation
}
?>
This code raises a fatal error because SQL_Result_mysql doesn't implement the abstract methods
of SeekableIterator (6) + Countable (1)
