> The <TT
CLASS="LITERAL"
>old_function</TT
> statement allows you to declare
a function using a syntax identical to PHP/FI2 (except you must
replace 'function' with 'old_function'.
</P
><P
> This is a deprecated feature, and should only be used by the
PHP/FI2->PHP3 convertor.
</P
><P
> Functions declared as <TT
CLASS="LITERAL"
>old_function</TT
>
cannot be called from PHP's internal code. Among other
things, this means you can't use them in functions such as
<A
HREF="function.usort.html"
><B
CLASS="FUNCTION"
>usort()</B
></A
>, <A
HREF="function.array-walk.html"
><B
CLASS="FUNCTION"
>array_walk()</B
></A
>, and
<A
HREF="function.register-shutdown-function.html"
><B
CLASS="FUNCTION"
>register_shutdown_function()</B
></A
>. You can get around
this limitation by writing a wrapper function (in normal PHP3 form)
to call the <TT
CLASS="LITERAL"
>old_function</TT
>.
