PHP进阶困惑
学习了HTML+CSS+JS,并学了PHP+MYSQL,还有smart和zend frameword等一些知识还没学,现在是想把这些学的知识综合练习,掌握好再继续往下学。
但是现在感觉自己还是什么都做不了, 基础知识不牢固,所以想巩固,想试着写一些功能模块,可是无从下手,是不是我忽悠了什么,找了一些源码,都不知道怎么下手去学习,而且源码的篇幅大,看起来特别难坚持,现在我该怎么做好了?有经验的前辈们指点一下小弟。
------解决方案--------------------
既然你都知道自己特难坚持了,那你也就知道自己的弱点啦...越难的东西就越要有勇气去克服。
------解决方案--------------------
要说“坚持”,那就是胡扯蛋了。编程这个玩意不是高考,是不能死记硬背的
编程的目的是要让计算机为你做事,而不是去当他的奴隶
从这个意义上讲,你是老师,计算机是学生。你不但需要反反复复地将你的意图告诉计算机,而且还需要清清楚楚的告诉计算机这一步干什么,下一步干什么
遇到问题绕着走,条条大路通罗马
你总有你掌握的比较好的知识,就从此出发。缺啥补啥,不要试图一口气吃成胖子

好吧,一般来说我喜欢看讨论,不过讨论太过偏题就不好玩了.
所以回到楼主的本意说两句个人看法,仅供参考.
1.一般来说学新知识前要知道并善于利用自己已经会的知识,所以楼主不妨透露一下你以前学过用过并且觉得还不错的东西....这样大家可以更有针对性地谈谈
2.计算机相关的知识都是实践性很强的,对我们这些应用开发者开说,更是如此,所以,做很大程度上比学更重要.
你的第一段,只看见学学学,"感觉自己还是什么都做不了","无从下手"....其实,做一个页面也是做....做点不是书上例子的完全自己的东西,感觉和收获是很不同的
3.只建议学习你正在用和即将要用的东西. 都知道软件,尤其是这些开源软件的升级是很快的,如果学了不很快用,很快它就成了落后的垃圾,下次要用时,你将不得不重新学. (综合第二点,学了不用也是学不好的)
而且,根据你的需要学,也能让自己能很好地规划自己的学习计划而不是盲目跟风...
4.大部分时候,我不建议孤立地学习别人的源码, 和上面差不多的道理. 根据自己的需要,适当地看一部分你需要看的代码. 那种从头一行行读....是糟蹋自己的时间/挑战自己的耐性/浪费女友的身体...... 除非你是有特别的目的....
5.我一般不挑战自我...所以,如果坚持不下去,可能就是错的...
------解决方案--------------------
个人意见现在你的理论知识已经足够了,随便找个东西去做,比如说留言板。
然后在现有的基础上不断的完善你的留言板,你会发现你的不足。
PS:别觉得留言板很简单,当你第十次进行修改的时候你再回头看下你的第一个留言板就会发现自己的进步所在。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

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),
