Operating System: *
PHP Version: 5CVS-2005-06-19
Assigned To: dmitry
New Comment:
Assigning by reference only works with variables and not expressions.
As @ starts an expression (as it requires to start and stop error
handling and therefore doesn't have a clean variable context) it makes
it extremely hard to support.
This behavior is quite general in PHP where variables that start with $
have more capabilities than expressions.
Sorry...

Description:
------------
When I run this code:
foreach (@$formErrors as &$formError) {
I get this:
parse error, unexpected '&', expecting T_STRING or T_VARIABLE or '$'
Something about using both the @ and the & in the same foreach loop. It
works with either one alone, just not both.
Reproduce code:
---------------
use the foreach on a non-existant array with references, and the @
statement modifier.
Expected result:
----------------
Should skip the foreach loop.
Actual result:
--------------
Doesn't work.
