php -r 'var_dump(count("foo"));'
outputs:
int(1)
so my strategy is usually
if (!empty($r) && is_array($r)) {
// good to go.
}
if I know it's an array I'll definitely use empty() over count() ....
count() needs to actually count the items where as empty() can return false
as soon as it finds a singel element ... maybe I'm mistaken - if so please
put me right.
