I love empty, because its fast and compact.
checking an array for a boolean value when a key does not exist, like here:
A:
if ( empty($foo['x']) ) echo 'no x';
this does not throw a notice that 'x' does not exist and is the fastest
variant compared to these two, even if 'x' exists. I especiall
Never use empty()
I've been burned by this too many times.
It's behaviour around '0' and friends changed over the years.
Some colleagues at a former job looked at me funny when they first
heard my rant about this. Then they tracked down 3 separate bugs and
fixed them, all deriving from the use

Hi,
I came across this:
echo sizeof(array());
echo sizeof("");
$a = "";

var_dump((array)"");
Results in:
array(1) {
[0]=>
