Hi!

I think the precedence of left and right associative operands can't be > compared. The switch between associativities already separates the

expression (if it could be explained this way).

Yes, this behaviour confused me. This is not common in other programming languages:

o  C         : invalid lvalue in assignment
o  Java      : required: variable
               found   : value

o JavaScript: invalid assignment left-hand side (Mozilla)

               syntax  error (Internet explorer)

But for me it isn't egxactly clear how the evaluation order was calculated (why doesn't the first = operator executed before &&). Does anybody know for example a flowchart, how it is implemented in PHP? Felho
