取消定义的功能 [英] undefining functions

问题描述

我有一个为我制作的每个网站运行的主脚本，并且它有一套标准的

功能集，但有时我会想要覆盖该功能以获得

特定网站，但如果我重新定义该网站，PHP会抱怨

覆盖功能。由于这是一个很好的警告，我不想删除

它，但我想要取消定义再次定义之前的功能。


喜欢：function_undefine（" drawbox"）;


或类似的东西。


有人有什么建议吗？

I have a master-script that runs for every site I make, and it has a standard
set of functions, but sometimes I would want to override that function for a
particular site, but if I redefine it for that site, PHP will complain about
overriding functions. Since that''s a good warning, I wouldn''t want to remove
it, but I would want to "undefine" a function before defining it again.

like: function_undefine("drawbox");

Or something like that.

Anyone got any suggestions?

推荐答案

你不想定义，取消定义和重新定义函数或

你有cpu周期浪费吗？ br />

将您的functions.inc拆分为模块化实体，您可以根据请求加载
。最后加载特定于站点的东西。


request_once（''func1.inc''）;

request_once（''func2.inc'' ）;

request_once（''func3.inc''）;

request_once（''spec1.inc''）;

request_once（ ''spec2.inc''）;


Sandman写道：

you don''t want to define, undefine and redefine functions or
do you have cpu cycles to waste?

split your functions.inc into modular entities that you can
load on request. load the site-specific things at the end.

request_once(''func1.inc'');
request_once(''func2.inc'');
request_once(''func3.inc'');
request_once(''spec1.inc'');
request_once(''spec2.inc'');

如果您的_sure_这是您想要的（请记住所涉及的开销

）解析

主脚本功能，即使它们没有被使用），查看变量

函数。


我相信这是可能的（如果我'，请纠正我我错了）...


主脚本：


函数foo_default（）

{

echo''blah blah blah'';

}

If your _sure_ this is what you want (bearing in mind the overhead involved
in parsing the
master-script functions even though they are not used), look into variable
functions.

I believe this is possible (correct me if i''m wrong)...

in master-script:

function foo_default()
{
echo ''blah blah blah'';
}
