move_uploaded_file上传的图片文件属性是600，无法访问，请高手指教。
问题如题。
还有一个奇怪的现象，就是这个问题出现在新服务器上，我在原来的服务器上是正常的，可以直接把属性改为644，而这里却是600，有遇到这个问题的高手指点一二。
------解决方案--------------------
如果租别人的服务器，就要让那边主事的帮你开通权限，你才能更改文件的权限。

可能是服务器设置问题

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
