Bug Type: Documentation Problem
Bug description:Assign by ref operator is missing in precedence table
Description:
------------
It seems that documentation is not clear about references.
There is no mentioning about
assign by ref
operator(http://php.net/manual/en/language.operators.precedence.php).
And its precedence is higher than instanceof.
Also, there is exists mentioning of left | & | bitwise and references.
What is a meaning of references in this line?
Test script:
---------------
$a = &$b instanceof stdClass;
$c = $d instanceof stdClass;
// line # * op fetch ext return
operands
//
-------------------------------------------------------------------------
// 3 0 > ASSIGN_REF $0 !0,
!1
// 1 FETCH_CLASS 84 :1
'stdClass'
// 2 INSTANCEOF ~2 $0,
$1
// 3 FREE ~2
// 4 4 FETCH_CLASS 84 :3
'stdClass'
// 5 INSTANCEOF ~4 !3,
$3
// 6 ASSIGN !2,
~4
// 7 > RETURN 1
