Hello

I've found a strange bug :

<?php
$string="01"; // and "02", "03", ... except "08" and "09"

echo ($string == 01)?1:0; // shows 1

$string="08"; // also for "09" but not other numbers

echo ($string == 08)?1:0; // shows 0
?>

Olivier

Numbers with leading zeros are considered octal where 08 and 09 are not allowed (and therefore evaluated as 0).
