为什么在$responseText=true;的情况下，
$mysign!=$sign,签名不相等，求解，加分
------解决方案--------------------
是你做sing数据有误，严格按照文档来做。支付的时候提交过去的数据和支付之后返回过来的参与验证的数据是否一致？ 跟CI无关的

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),
