I don't know if you noticed that but 

if(condition); 

works. It won't give out any error or warning, while using the currently latest version (4.04pl/win). 
I don't know if that's the intention of the programmers but IMO it's more likly a bug, since it doesn't make any sense anywhere i could think so far.
Please let me know if that's fixed soon.

Yes, this is a valid construct. The syntax of if operator is:
'if(' expression ')' statement

';' alone is a valid statement (just like in C). So that
code is valid. PHP cannot really determine if it's
"meaningful" or not for you.
