很多站长朋友们都不太清楚phpcompat，今天小编就来给大家整理phpcompat，希望对各位有所帮助，具体内容如下：
本文目录一览： 1、 php函数如何返回数组啊， 比如， 2、 php 内置大概多少个常量 3、 Sublime Text，php代码格式化插件codeformatter 设置PHP代码格式时报错 怎么处理 4、 php rpc好用吗,有什么优缺点?php rpc框架哪个好? php函数如何返回数组啊， 比如，$a = array();
$a[] = "项目";
$a[] = "标题";
$a[] = "时间";
return $a
php 内置大概多少个常量每个版本的内置常量都例不有同的，要看具体的版本。这些是我收集到的。大概有250个左右吧。参考参考。

php rpc好用吗,有什么优缺点?php rpc框架哪个好?什么是RPC框架？ 如果用一句话概括RPC就是：远程调用框架（Remote Procedure Call）那什么是远程调用？通常我们调用一个php中的方法，比如这样一个函数方法: localAdd(10, 20)，localAdd方法的具体实现要么是用户自己定义的，要么是php库函数中自带的，也就说在localAdd方法的代码实现在本地，它是一个本地调用！远程调用意思就是：被调用方法的具体实现不在程序运行本地，而是在别的某个远程地方。
远程调用原理
比如 A (client) 调用 B (server) 提供的remoteAdd方法：
首先A与B之间建立一个TCP连接；
然后A把需要调用的方法名（这里是remoteAdd）以及方法参数（10， 20）序列化成字节流发送出去；
B接受A发送过来的字节流，然后反序列化得到目标方法名，方法参数，接着执行相应的方法调用（可能是localAdd）并把结果30返回；
A接受远程调用结果,输出30。
RPC框架就是把我刚才说的这几点些细节给封装起来，给用户暴露简单友好的API使用。
远程调用的好处
解耦：当server需要对方法内实现修改时，client完全感知不到，不用做任何变更；这种方式在跨部门，跨公司合作的时候经常用到，并且方法的提供者我们通常称为：服务的暴露。
RPC与Socket有什么区别？
通过上面的简单阐述，好像RPC与Socket 好像啊。都是调用远程的方法，都是client/server模式，我之前也写了一篇文章: 细说socket 那他们有啥区别呢?
RPC（远程过程调用）采用客户机/服务器模式实现两个进程之间相互通信。socket是RPC经常采用的通信手段之一，RPC是在Socket的基础上实现的，它比socket需要更多的网络和系统资源。除了Socket，RPC还有其他的通信方法，比如：http、操作系统自带的管道等技术来实现对于远程程序的调用。微软的Windows系统中，RPC就是采用命名管道进行通信。
RPC与REST有什么区别？
通过了解RPC后，我们知道是RPC是client/server模式的，调用远程的方法，REST也是我们熟悉的一套API调用协议方法，它也是基于client/server模式的，调用远程的方法的，那他俩又有啥区别呢？
REST API 和 RPC 都是在 Server端 把一个个函数封装成接口暴露出去，以供 Client端 调用，不过 REST API 是基于HTTP协议的，REST致力于通过http协议中的POST/GET/PUT/DELETE等方法和一个可读性强的URL来提供一个http请求。而 RPC 则可以不基于 HTTP协议
因此，如果是后端两种语言互相调用，用 RPC 可以获得更好的性能（省去了 HTTP 报头等一系列东西），应该也更容易配置。如果是前端通过 AJAX 调用后端，那么用 REST API 的形式比较好（因为无论如何也避不开 HTTP 这道坎）。
php中流行的rpc框架有哪些
既然php是世界上最好的语言，那php中流行的RPC框架有哪些呢？
先列举下： phprpc，yar, thrift, gRPC, swoole, hprose
因为时间和精力有限，不可能一个一个的去学习和使用，我选几个世面上用的最多的几个用下吧。因为RPC原理是一样的，都是Client/Server模式，只是每个框架的使用方式不一样而已。
