Operating system: linux-2.2.14pre16 + some patches
PHP version: 4.0.0 Release
PHP Bug Type: Misbehaving function
Bug description: !1 could return 0 instead of false
hello,
!1 returns false now in php4.0 so it's not outputted in echo (echo "!1: " . (!1) .
"\n"; ) whereas in php3.x !1 returned 0 and was displayed.
i know this is not a bug, but it may render many scripts (including the ones i'm working on
(~50.000 lines)) misbehave in certain conditions and definitely is a compatibility problem.
_checking_ and changing !<some_expression> to (int)!<some_expression> would take
*LOTS* of time, so IMO this behaviour should be changed or at least be configurable via some option.
or the way echo outputs boolean could be changed. please, don't make php programmers go
berserk :)
thanks,
Michal Vitecek
