My quick tests show that !$array is significantly faster, as you'd
expect, based on variants of this loop:
for( $i = 0; $i < 100000; $i++ ) { !count( $array ); }
However, if checking whether an array is empty is a bottleneck in your
program, you deserve a small prize for the weirdness of your
optimization problems.
