很多时候一门技术的瓶颈都不在其本身。我有一个朋友遇到过这样的问题:./script.sh && binary.binscript.sh 中 export 的变量在 binary.bin 中没有生效,相信诸位已经看出问题出在哪里。
对于我的这位朋友,需要做的不是回去复习 SHELL 编程。而是要把 fork() 和 execv() 的工作机制搞清楚,才能举一反三,不被相似问题卡住。
所以我的建议是,先多学些其他方面的知识,再写 PHP 感觉就不一样了。 试试yii 调侃一下。
你问题里说到的什么深入的了解PHP什么的。。完全是外行人跟你说的吧?PHP无非是一个工具。一个真正的裁缝,不会跟你说,要深入的研究剪刀如何使用吧?
对于以上的问题,我的回答就是以上几句话,然后说点题外话。
踏入软件开发这个行业,门槛其实很低,学一门语言,学会SQL,会对数据库做曾删改查,那你就入行了。。是的,就这么简单。但是,做好一个项目,你要学的东西远远不止这些。当然,你也要给自己定一个方向,毕竟一个优秀的项目不是你一个人一个角色就能完成的。
大概列一下,这个行业内你能选的角色,按重要程度,以及难度系数排序:
- 系统分析师 一个需求都明确的项目,有什么好说的?能把什么东西都理顺,并且,能让整个团队沿这个方向走的人,你说有多重要吧。
- 系统架构师 让系统有优秀的基因,这个是架构师干的。
- 算法工程师 这个放第三个,是因为难度高个人认为。但是,对于小项目或者,对于性能要求不高的项目来说,这个角色。。。还真可有可无。
- DBA 让一切数据井然有序。这年代,数据有多重要大家都懂的。
- 普通的开发人员 效率,经验,少出错。
- 测试人员 效率,经验,找出错。
- 产品经理 这个放最后面,是因为。这个岗位可以不懂技术,对于产品经理来说,运营方面的能力要比技术方面的能力更重要。
方向定了,你会迷茫的东西也就少了。学习上的瓶颈,会变成工作效率或者能力上的瓶颈,两者瓶颈对于自身的压力是不同的,压力越大,突破瓶颈的速度也会越快(如果,觉得自己突破不了这个瓶颈,那你就不要干了。。。。)。 去找正确的问题,届时自然会知道该学什么 我要说PHP本来就没太多可深入的余地了题主会不会打我…
真要深入就深入到它的周边吧。学习如何在php上做性能调优,学习怎么判断运行的性能瓶颈。学习数据库的优化。学习memcache等kv数据库的使用。 其实, 我觉得(不一定对哈) 技术 起源于 需求. 所以, 当你考虑下一步要学什么的时候, 应该问自己: 你还需要啥? 你的业主需要啥? 未来你需要啥? 很简单, 缺啥补啥.
例如, 你觉得PHP效率太低, 有如下方法: PHP C扩展, 直接C, 换其它脚本
如果你觉得网络太慢, 这是典型C10K, 可以: PHP加速器,其它优化(一般是缓存), 换编程架构(事件驱动), RPC扩展(听过没用过) , 分布式(我好想了解具体), 其它..
如果你觉得现在的网站功能太弱, 喜欢浏览器极致体验, 可以: 学习js/css, 学习交互设计..(我真不知道了)
如果你觉得网站不安全, 可以: 关注SQL注入, XSS注入, 目录遍历, 内存溢出(C), 等等其它
所以, 你想学啥? 1.自写框架
2.c/c++
写了多少代码只是过程,关键看写的是什么,产生了什么结果,你得到了哪些领悟,
关键还是思想,就是一个问题,能够分析出瓶颈在哪,如何去解决(不只是PHP范围) eyeOS
看完这个系统, 就知道自己还有多少路要走了 才3ooo行代码,对lnmp架构如何,如何优化mysql,php底层机制。linux下的php,还有自己能否写个框架,看看一些开源的代码。有很多,小伙子不要浮躁,

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.
