如果有会经常变化的设置项,也许在不同的环境中,将它们放在一个文件中,然后从文件中读取它们,就好像它们是环境变量一样
PHP——2(PHP变量作用域) PHP——3(PHP变量分离/引用(Variables Separation)) 为辅助阅读,可直接跳过 回顾一下zval的结构: struct _zval_struct...那么对于它来说,效率和资源占用率是一个很重要的衡量标准,也就是说,PHP必须尽量介绍内存占用率,考虑下面这段代码: PHP的开发者也看出来了: 我们之前讲过,PHP中的变量是用一个存储在symbol_table中的符号名,对应一个zval来实现的,比如对于上面的第一行代码...PHP提供了一个函数可以帮助我们了解这个过程debug_zval_dump: PHP是以传值的形式穿参数的。
或许你知道,或许你不知道,PHP是一个弱类型,动态的脚本语言。...所谓弱类型,就是说PHP并不严格验证变量类型(严格来讲,PHP是一个中强类型语言,这部分内容会在以后的文章中叙述),在申明一个变量的时候,并不需要显示指明它保存的数据的类型: PHP并不是独立运行的,要运行PHP我们需要PHP解析器: /usr/bin/php -f example.php 我前面的文章中已经讲过,PHP的执行是通过Zend engine...那么PHP是如何在ZE的基础上实现弱类型的呢? 首先要声明一点,如果你以前没有接触过PHP的源码分析,扩展开发。...如果你并不了解PHP的架构, 没有听说ZE,那么我建议你先看看我前面的文章,尤其推荐: 深入浅出PHP(PHP Internals) 深入理解PHP原理之Opcodes 在PHP中,所有的变量都是用一个结构
的变量的内部表示(深入理解PHP原理之变量(Variables inside PHP)),以及PHP中作用域的实现机制(深入理解PHP原理之变量作用域(Scope inside PHP))。...我们知道,对于简单变量,PHP是以传值的形式穿参数的。...这就是PHP的copy on write机制: PHP在修改一个变量以前,会首先查看这个变量的refcount,如果refcount大于1,PHP就会执行一个分离的例程, 对于上面的代码,当执行到第三行的时候...那么,对于PHP中的引用,那又是如何实现呢?...;) 这次我们介绍了PHP的变量分离机制,下次我会继续介绍如果在扩展中接收和传出PHP脚本中的参数。
environment file matching the APP_ENV exists...environment file...variables if we're immutable // Ruby's dotenv does this with `ENV[key] ||= value`....所以 Dotenv默认情况下不会覆盖已经存在的环境变量,这个很关键,比如说在 docker的容器编排文件里,我们会给 PHP应用容器设置关于 Mysql容器的两个环境变量 environment:...因为如果php.ini中的 variables_order配置项成了 GPCS不包含 E的话,那么php程序中是无法通过 $_ENV读取环境变量的,所以使用 putenv动态地设置环境变量让开发人员不用去关注服务器上的配置
Unlike local variables, which are stored in a special data structure in the interpreter, global variables...Lua is the ability to change this table per-function, so the function sees a different set of global variables...As an example, here's a function that sets its environment to a custom one and uses variables from it...global variables (including the standard functions) are not in the new env a = 2 -- create a new...This is why 5.2's load function takes a parameter that lets you set the chunk's _ENV to a custom table

php的配置文件php.ini的配置项为:variables_order = “GPCS”。...想让$_ENV的值不为空,variables_order的值应该加上一个大写字母“E”,即:variables_order = “EGPCS”。...EGPCS是Environment、Get、Post、Cookies、Server的缩写。...如果variables_order 的配置中缺少E ,则PHP 无法接受环境变量,那么$_ENV 也就为空了。 生产环境不推荐使用EGPCS。...推荐使用getenv (string $varname)函数来获取Environment中的值。
