I think this should be
if(!empty($var1)) is true if $var1 is set to anything except a null string, 0
or the string '0'
It would be great, unless I've missed the point somewhere along the line, if
empty treated '0' (string) as not empty, then the function could be used for
checking user input where the string '0' is perfectly valid. In thousands of
lines of PHP code I haven't been able to use empty() once - I always end up
going
if(isset($var) && strcmp($var,''))...
Just a dream :)
