Ben son zamanlarda web üzerinde bulunan bazı kodları okuyan ve bu php sözdizimi üzerinde geldi:

<?php $framecharset && $frame['charset'] = $framecharset; ?>

Can someone explain what is going on in this line of code? What variable(s) are being assigned what value(s), and what is the purpose of the && operator, in that location of the statement?

Thanks! Pat
