To return a reference from a function, you have to use
the reference operator &amp; in both the function declaration and
when asigning the return value to a variable:
<informalexample>
<programlisting role="php">
function &amp;returns_reference() {
return &amp;$someref;
}
$newref = &amp;returns_reference();
</programlisting>
