like a large array inside a tight loop. Since PHP 4, assignment
by reference has been supported, using the <computeroutput>$var =
&amp;$othervar;</computeroutput> syntax, but this is not possible
in PHP 3. 'Assignment by reference' means that both variables end
up pointing at the same data, and nothing is copied anywhere.
