If you wish to pass a variable by reference to a function which
does not do this by default, you may prepend an ampersand to the
argument name in the function call:
<informalexample>
<programlisting role="php">
<![CDATA[
function foo ($bar)
{
$bar .= ' and something extra.';
}
$str = 'This is a string, ';
foo ($str);
echo $str; // outputs 'This is a string, '
foo (&$str);
echo $str; // outputs 'This is a string, and something extra.'
