define() vs. const
...ression as name. This allows to do things like this:
for ($i = 0; $i < 32; ++$i) {
define('BIT_' . $i, 1 << $i);
}

...PHP creates a 16-byte long unique identifier number (stored as a string of 32 hexadecimal characters, e.g a86b10aeb5cd56434f8691799b1d9360) for an individual session.
