First off, sorry if this is answered somewhere else. I did a brief search, but wasn't sure how to ask in search terms.
I'm looking at some code and came across lot's of statements like this:
if ( ($a != empty_or_null_or_notDefined && $a == 5 )
Is this the same as just saying:
if ( $a == 5 )
?
(language is PHP.)
