Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
You need to use the @ where the error happens. Here it is the passing
to the function or in other words the function call and not the
access:
php -r 'function test(& $a) {} $b="hello"; @test($b[0]);'

Description:
------------
@ in argument passed into function prevents 'Fatal error: Only
variables can be passed by reference' error.
Reproduce code:
---------------
function test(& $a) {
echo $a;
}
$b = "hello";
test($b); // hello
test($b[0]); // 'Fatal error: Only variables can be passed by
reference'
test(@ $b[0]); // h
Expected result:
----------------
'Fatal error: Only variables can be passed by reference'
Actual result:
--------------
test(@ $b[0]); // h
