Bug description:clone operator precedence is wrong
Description:
------------
---
From manual page: http://www.php.net/language.operators.precedence
---
According to the Operator Precedence table, the clone operator has higher
precedence than [.
This would mean clone $arraylike[0] is evaluated as ( clone $arraylike
)[0], but
it seems that the implementation does clone ( $arraylike[0] ). I think this
is
probably correct behavior, so I conclude the documentation is incorrect.
Test script:
---------------
$a = array( new stdClass() );
clone $a[0];
Expected result:
----------------
in this case, some type error at runtime since you can't clone an array
Actual result:
--------------
the object at offset 0 is cloned
