Bug #16697 Updated: %= operator

ID: 16697 Updated by: tal@php.net Reported By: spagnoli@dualservice.it -Status: Open +Status: Bogus Bug Type: *Math Functions Operating System: Linux PHP Version: 4.0CVS-2002-04-19 New Comment: Not a bug > bogus. $a = ++$b = 1 is meaningless, you cannot assign values to ++$b or $b++. -Tal Previous Comments: ------------------------------------------------------------------------ [2002-04-19 08:04:01] spagnoli@dualservice.it I've tried a trick I often use in C++; the PHP syntax should be identical: $a=0; while ([condition]) { $mystring= ++$a%=8 ? "A" : "B"; [...] } the value of $mystring should be "B" seven times and then "A" once, keeping the value of $a in the range [0..7]. If $a is useless for other purposes, the following gives the same result: $a=0; while ([condition]) { $mystring= ++$a%8 ? "A" : "B"; [...] } whith two differences: $a is no loger necessarily in the range [0..7] and, above all, tha latter works, but tha former doesn't! I've tried to parse "++$a" writing $mystring= (++$a)%=8 ? "A" : "B"; but it doesn't work. Since this problem is related to operators, I don't think you need information about my modules or my system, but if I'm wrong ask me for that. Thank you.
