No matter how silly it can looks like (a = a++) it is still completely valid code and it SHOULD run without problems.Yeah, it's a valid as: $a = $a; and does the same thing, which is nothing. If you want a statement that does something, then use: $a = ++$a; or simply: $a++; or ++$a; Any of those will increment $a, whereas ($a = $a++;) does nothing.
