Many old code examples dating back to PHP3 use this construct:
while(list($x,$y)=each($a)) {...}
However, on PHP4 and PHP5, you have this construct:
foreach($a as $x=>$y) {...}
The latter construct is almost twice as fast as the former, with the usual caveats about
architecture and compiler and whatnot having an effect.
