在OOP中包含配置变量 [英] Including config variables in OOP
问题描述
我刚刚开始在我的网络应用程序中使用OOP，而且我遇到了一些棘手的问题。
我想要一个单独的我所有配置变量的文件。
其中一些是为数据库操作重新映射表名。
$ session_tbl =''sessions'';
$ users_tbl =''用户'';
等...
现在在我的班级定义中我试图找到一种方法在构造中包含这个
文件，我得到通知，当需要它们时，它们没有被定义，并且它会破坏代码。
我尝试过使用公钥。
public $ session_tbl =''sessions'';
public $ users_tbl =' '用户'';
我得到了：
解析错误：语法错误，意外T_PUBLIC
当我在方法中声明一个公共var时，我通常会得到它。
所以这不起作用。
我已经使它工作了但是在每个需要配置数据的方法中，在
中放置一个单独的include语句。
但是我有一些方法需要文件然后它
调用另一个需要文件的方法所以我得到很多包括调用
在一个脚本中活动。
例如：
class auth（）{
公共函数方法 - 1（）{
包含file1
*代码*
}
公共函数方法 - 2（）{
包括file1
*代码*
$ this-> method-1（）;
}
}
我不确定这是一个更好的方法，所以任何帮助都将是
赞赏。我可能会说错了。
谢谢

I have just recently started to use OOP for my web applications and am
running into some head scratching issues.
I wanted to have a separate file for all my configuration variables.
Some of them being remapping table names for DB operations.
$session_tbl = ''sessions'';
$users_tbl = ''users'';
etc...
Now in my Class definition I was trying to find a way to include this
file in the construct and I get notices that they are not defined when
they are needed and it breaks the code.
I''ve tried using the public key word.
public $session_tbl = ''sessions'';
public $users_tbl = ''users'';
And I get a:
Parse error: syntax error, unexpected T_PUBLIC
Which I usually get when I declare a public var inside a method.
So that did not work.
I have made it work however by placing a separate include statement in
each method that needs the configuration data.
But I have a few situations where a method needs the file and then it
calls another method that needs the file so I get numerous include calls
in a single script activity.
for example:
class auth() {
public function method-1() {
include file1
*code*
}
public function method-2() {
include file1
*code*
$this->method-1();
}
}
I am not sure of a better way of doing this, so any help would be
appreciated. I may be going about it all wrong.
Thanks
