This function returns an multidimensional array containing a list of
all defined functions, both built-in (internal) and user-defined. The
internal functions will be accessible via
<varname>$arr["internal"]</varname>, and the user defined ones using
<varname>$arr["user"]</varname> (see example below).
<informalexample>
<programlisting role="php">
function mytable($id, $data) {
