If the expression on the right side that produces a Closure has side effects (output, DB interaction, etc.), then the order in which those side effects happen may change with the different restructuring.
That is a good point. I see you added a precedence section, but this
does not fully explain the order of operations in face of side-effects
and more generally with regard to “short-circuiting” behavior. An OPcode
dump would explain that.
Specifically for:
function foo() { echo __FUNCTION__, PHP_EOL; return 1; }
function bar() { echo __FUNCTION__, PHP_EOL; return false; }
function baz($in) { echo __FUNCTION__, PHP_EOL; return $in; }
function quux($in) { echo __FUNCTION__, PHP_EOL; return $in; }
foo()
|> (bar() ? baz(...) : quux(...))
|> var_dump(...);
What will the output be?
