Re: PHP boolean's

..oO(Rik Wasmus)

One could even argue using if(count($someArray) == 0) is better, as
empty() will not only work for arrays , but for a whole list of empty
values ('',0,null, etc.). Using the count function does immediatly issue
an error (non-fatal) when $someArray is not an array, making it more easy
to track bugs and errors. That being, said, I usually do use empty()
though :).

ACK

The only annoying thing (IMHO) about empty() is that it only works on
variables, but sometimes I want to directly check a function result.
So I had to write a little helper function:

function isEmpty($var) {
return empty($var);
}

Now I can do things like

if (isEmpty(getSomething())) {
...
}

where the normal empty() would complain.
