osadmin的目录如下
注意
index.php在uploads目录下,
init.inc.php在uploads/include目录下
config.inc.php在uploads/include/config目录下
index.php:
require ('./include/init.inc.php');
init.inc.php:
require 'config/config.inc.php';
按理说访问index.php页时,寻找config.inc.php页的路径应为uploads/config/config.inc.php,是一个错误路径,但为什么实际运行确能找到?各位能解释下是怎么找到的吗。
难道解析这种既不是绝对路径,又不是相对路径的的路径,还有什么基情。
(补充)include_path:‘.;C:\php\pear’
回复讨论(解决方案)
init.inc.php:
require 'config/config.inc.php';
init.inc.php里面不是包括了config.inc.php 么,当然能找到啦。
php不是参照入口文件的路径吗?也就是说 在找config.inc.php时应该是按“uploads/config/config.inc.php”这个路径找,但显然这个路径不存在,存在的是“uploads/include/config/config.inc.php”。难道不是这样?
require 'config/config.inc.php';
不是在 init.inc.php 中执行的吗?
所以既然只有 uploads/include/config/config.inc.php 存在,当然就加载他了
你#2的描述是正确的
如果你有 uploads/config/config.inc.php 文件,那么这个文件将被优先加载
也就是说,你可以用这种方法干预应用系统的行为
下面是用我的伪代码描述require请求文件的处理,看对否:
相对路径:前面带./或者../的路径,如'./include/init.inc.php'
伪相对路径:前面不带./或者../且又不是绝对路径的路径,如'config/config.inc.php'
当前工作目录:web环境下,即入口文件所在目录
if(path为绝对路径){ file_path=path;}else if(path为相对路径){ file_path=conbine(当前工作目录,path);}else{ //伪相对路径 dir_list=include_path; dir_list.add(当前工作目录); dir_list.add(调用语句所在目录); foreach(dir_list as dir){ temp_path=conbine(dir,path); if(temp_path存在){ file_path=temp_path; return; } }}
访问index.php页时
require 'config/config.inc.php';
其实生效的是
file_path=conbine(调用语句所在目录,path)
这里调用语句所在目录,即init.inc.php文件所在目录,从而正确找到文件。
是的,是这样的

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
