Is there a difference between:
function someMethod( $someArg ) {
// some code
return;
}
and
function someMethod( $someArg ) {
// some code
// no return
}
Both have NULL
as 'return value'. Is there a difference? Something PHP internally? Performance? Speed?
edit
I ask, because in Zend framework (in this video) they use return;
which seemed (seems) silly to me. However, you would think that the people behind Zend framework do know their PHP...
