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.
警告 |
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.
