PHP中的宏 [英] Macros in php

问题描述

有没有希望新版本的PHP

会支持类似于C或C ++的宏？

我已经搜索了手册并且没有找到任何内容

除了define指令外，它可以用

来定义常量值。

当然它不是必需的功能，

但它可能非常有用。

Is there any hope that new versions of PHP
will support macros similar to C or C++?
I''ve searched manual and didn''t find anything
except define directive, but it can be used
to define constant values only.
Of course it is not THAT neccessary functionality,
but it could be very useful.
