取消声明PHP中的类 [英] Undeclare a class in PHP

问题描述

我有一个守护程序在后台处理相当多的MVC逻辑，其中包括它需要的类.但是，有时甚至会在一个循环中包含来自不同模块的两个名称相同的类.理想情况下，如果可能的话，我想在再次包含它之前先取消声明"一个类，但是如果可以的话，我在PHP手册中找不到.

类似这样的东西:

//first foo 
class foo(){ 

} 

//undeclare foo 
undeclare foo; 

//create new foo 
class foo(){ 

} 

解决方案

无法取消声明"一个类.

您可能应该研究PHP的名称间隔，或者使用类似的约定来命名您的类

Application_Module_Class

所以你会打电话给

$x = new Application_Foo_Bar;

包括Foo模块中的Bar类

这也很适合使用自动加载函数

I have a daemon processing quite a bit of MVC logic in the background that includes the classes it needs on demand. Sometimes, however, it comes to a point where it includes two identically named classes from different modules within one cycle. Ideally, I would like to "undeclare" a class before I include it again, I cannot find in the PHP manual however, if this is possible.

Something like this:

//first foo 
class foo(){ 

} 

//undeclare foo 
undeclare foo; 

//create new foo 
class foo(){ 

} 

解决方案

It is not possible to "undeclare" a class.

You should probably look into PHP's namespacing or, use a convention for naming your classes similar to

Application_Module_Class

so you would be calling

$x = new Application_Foo_Bar;

to include the Bar class from the Foo module

This also lends itself quite well to using autoload functions
