> Functions declared as <TT

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"

<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
PHP 3 form) to call the <TT
CLASS="literal"
>old_function</TT
>.
