PHP码农一枚,工作半年,现在只会基本的增删改查,遇到某些问题也能自己解决,但是感觉进步很慢,一直也在看经典的技术书籍,(比如《代码大全》),深入原理的例如《PHP核心技术与最佳实践》,但是问题是看书当时能懂,可是每次写代码的时候就想不到去将这些知识融入到自己的实践当中,感觉知识的利用率很低,进步很慢。
另外,想摆脱当前这种局面,想更进步一些,有哪些好的,可操作性的方法?
回复内容:
如果你的工作很枯燥,只能用简单的知识的话,你只能在业余时间创造困难来用这些知识了。自己写点难写的小软件啥的。 几点建议,希望对你有用:1、看书应该深入去看深入语言本身、开发思想、经验方面的书籍,教你如何如何这种书不用太认真,要看教你为什么的书。
2、自己尝试做一些规模不大、有挑战的项目,遇到问题先独立解决在搜索别人的解决方案。
3、阅读并分析优秀的开源项目,分析作者的设计思想。
4、要做到融会贯通只能靠不断编码、不断总结!

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

Setting the httponly flag is crucial for session cookies because it can effectively prevent XSS attacks and protect user session information. Specifically, 1) the httponly flag prevents JavaScript from accessing cookies, 2) the flag can be set through setcookies and make_response in PHP and Flask, 3) Although it cannot be prevented from all attacks, it should be part of the overall security policy.

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

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),
