# `old_function`

The `old_function` statement allows you to declare a function using a syntax identical to PHP/FI2 (except you must replace 'function' with 'old_function'.

This is a deprecated feature, and should only be used by the PHP/FI2->PHP 3 convertor.

Внимание
Functions declared as `old_function` cannot be called from PHP's internal code. Among other things, this means you can't use them in functions such as usort(), array_walk(), and register_shutdown_function(). You can get around this limitation by writing a wrapper function (in normal PHP 3 form) to call the `old_function`.

`For everybody who want to know old_function's syntax, here it is:
old_function name $param1, $param2, ..., $paramn ( code;);
eg.:
<?
old_function eq $param, $param(
if($param1==$param2)
echo "equal";
else
echo "not equal";
return ($param1==$param2);
);
eq(1,2);
?>`
