为什么是PHP是全世界最好的语言,那你说说,好在哪里?
「为什么在笑话里这个程序员不说 C++ / Python / Haskell 或者别的什么语言是最好的而要说 PHP是最好的呢?」——因为说任何其他语言「最好」都并不好笑啊。
任何掌握超过两种以上非 PHP 编程语言且具有一定常识的程序员都会本能地意识到 PHP 的问题所在,曾经有一篇汇总性的文章在此: PHP: a fractal of bad design / fuzzy notepad (译文版可见:五大受损, 全面解析PHP的糟糕设计,但翻译得很烂)
历陈 PHP 破败之处,激荡深远。如果你没时间去读那篇长文,那我告诉你一个简单的例子来说明 PHP 有多匪夷所思:PHP 的核心函数命名很不一致,有 「strptime」这样类 C 函数的名字,有「nl2br」这样的简写,却也有「htmlspecialchars」这样的长名。
后来人们发现这种不一致并非偶然,而是当 PHP 还是只有不到一百个函数的小语言的时候,其作者决定用函数名的字符数量——来作为函数的 hash(!)。由于这个愚不可及的决定,PHP 的函数名长度要尽可能地长短有秩、均匀分布,影响一直延续至今[0]。
甚至有好事者将上述文中:You pull out the hammer, but to your dismay, it has the claw part on both sides.
这一句严肃对待,做了一把 PHP 锤子:
试想你走进五金从业者公会的啤酒馆,看到墙上挂着从钉子到电动螺丝刀的各式工具当作陈列品,而你在端详一阵之后指着其中的这样一把锤子,说「啊,这是最好的工具」,你觉得酒馆里的人会是什么反应呢?

谁告诉你php是全世界最好的语言?
写过几年php,说说它好处:
- 简单,学习简单,概念少,没有什么多线程啊,异步之类的。
- 帮助手册好用,php文档手册是我用过的最好用的手册。查询方便,介绍详尽。
- 数组用起来爽。
- 部署简单。更新的时候只需要丢个文件上去就行。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3.

Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
