Extracts variables as references. This effectively means that the
values of the imported variables are still referencing the values of
the <parameter>var_array</parameter> parameter. You can use this flag
on it's own or combine it with any other flag by OR'ing the
<parameter>extract_type</parameter>. This flag was added in PHP
4.3.0.
