HomeBackend DevelopmentPHP Tutorialget_include_path()是什么意思?该如何处理

get_include_path()是什么意思?
这段代码 set_include_path(INCLUDE_PATH . PATH_SEPARATOR . get_include_path());

我百度了下说是可以对include和require的路径范围进行限定
但是我echo get_include_path(); 输出的是F:\AppServ\www\iwb/application/;.;C:\php5\pear
后面的;.;C:\php5\pear算是什么啊?

------解决方案--------------------
paer是PHP的库,这个库提供了很多现成的封装对象,类似Javascript的JQuery。当你要使用这个库时,就可以把库文件放在C:\php5\pear,而不用放在网站目录里。
------解决方案--------------------
get_include_path 函数返回当前 php 的搜索路径(通常就是 php.ini 中的 include_path)

当没有另外设置 include_path 时, php 默认 include_path 为 .;C:\php5\pear(window系统中)

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
