Summary: Ternary operator will not work with return by
reference

This is a general problem with reference inside ternary operator. For ex., the
following script fails with the same error:
$link = isset($i) ? (& $arr[$i]) : null;
- while the following works fine:
$link = & $arr[$i];

Description:
------------
PHP fails to parse a returned by reference value when using the ternary
operator.
The test script provided illustrates a case of when it is absolutely necessary
to return by reference; if the "&" is removed then the output would be a fatal
error: "Fatal error: Cannot use [] for reading in <...>"
Test script:
---------------
$value = ($condition)?(
$some_value
):(&$object->Collection[]);
Expected result:
----------------
No errors, should be the equivalent of having:
if($condition){
$value = $some_value;
}else{
$value = &$object->Collection[];
}
Actual result:
--------------
Parse error: syntax error, unexpected '&' in <...>
