很多朋友在安装destoon的时候出现“Internal Server Error”的错误提示信息，导致无法安装，其解决方法如下：
方法一、删除根目录下.htaccess文件，如果无效，请尝试方法二；
方法二、对于Liunx/Unix服务器，如果不支持0777属性，可修改根目录config.inc.php：
$CFG['file_mod'] = 0777;
改为：
$CFG['file_mod'] = 0755 ;
然后，FTP修改已经被系统自动修改为0777属性的目录和文件为0755属性。

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AMDependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
