Hi
Is there anything that can manipulate a variable bit by bit? If have a
variable $x that has to switch between two values. It doesn't matter if
it is true or false, 0 and 255 or whatever. Normally the easiest way
would be to use xor to have the variable switch between both states but
I couldn't find anything like that in the reference.
Does PHP support such kind of bit manipulation? Or does anybody know
another way to have the variable switch on an easy way? I know that it
is possible with several if...thens but I'm looking for an easier and
faster way. Thanks for your answers and help.
Mika
