folgendes Test-Script:

=== schnipp ===
include "class.timer.php";
$t = new Timer;
unset($array);
for ($i = 0; $i < 100000; $i++)
{
        $array[] = $i;
}

reset($array);
unset($test);
$t->new_timer("While-Schleife", 1);
while (list($key ,$val) = each ($array))
{
        $test = $val;
}
$t->stop();

reset($array);
unset($test);
$t->new_timer("Foreach-Schleife", 1);
foreach ($array AS $key => $val)
{
        $test = $val;
}
$t->stop();

$t->echoalltimers();
=== schnapp ===
