Output of the code is correct in that machine and PHP version. Code also tested by _RainMkr_ (from #php) using PHP 4.0.6 under Linux 2.4.5 Need feedback on whether other numeric programs have similar problems under that version of Debian. ------------------------------------------------------------------------ [2001-11-20 04:47:13] derick@php.net Works fine for me, can you try the RC from www.php.net/~zeev/php-4.1.0RC3.tar.gz ? Derick ------------------------------------------------------------------------ [2001-11-20 04:43:47] mail-php.net@kimihia.org.nz There seems to be some voodoo in this script ... for ( $i = -7 ; $i < 28 ; $i ++ ) { $day = date('d'); print "\ndate is $day "; $day = $day + $i; print " after adding $i is $day "; } And output ends up looking like so: date is 20 after adding -7 is 135122101 ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=14138&edit=1
