让PHP 多语言 【转】
原文地址:http://www.laruence.com/2009/07/19/1003.html
开发多语言的Web应用是一件非常困难的事,各个国家的字符集的编码方式、货币符号、日期格式、数字格式、文字表现都各不相同.
我们今天用一个简单的实例说明一下在PHP中的getText的用法(getText是一系列的工具和库函数,帮助程序员和翻译人员开发多语言软件的), 从而实现PHP的i18n.
现在, 我们假设要显示一个返回主页的link:
//home.php: $str = 'home'; print {$str} HTML;下面开启我们多语言的开发之旅:
创建pot文件,pot是Portable Object Template的首字母缩写,与po对应的是mo,mo是Machine Object的首字母缩写。前者意指原始的字符串文件,一般用于给翻译人员去修改的,后者则是与机器相关的,一般是供程序读取。可以手工创建pot文件,也可以通过xgettext从代码中抽取字符串来产生。这里是用xgettext来产生的:
xgettext -a home.php -o home.pot
运行该命令后,我们发现,在当前目录下,产生了一个名home.pot的文件,打开该文件,可以看到:
# SOME DESCRIPTIVE TITLE. # Copyright (C) YEAR THE PACKAGE'S COPYRIGHT HOLDER # This file is distributed under the same license as the PACKAGE package. # FIRST AUTHOR根据pot产生不同语言的po文件,这里我们先产生一个简体中文的po文件:
export LANG=zh_CN.gb2312
msginit -l zh_CN.gb2312 -i home.pot
运行该命令后,我们发现,在当前目录下,产生了一个名zh_CN.po的文件,打开该文件,可以看到:
# Chinese translations for PACKAGE package # PACKAGE 软件包的简体中文翻译. # Copyright (C) 2009 THE PACKAGE'S COPYRIGHT HOLDER # This file is distributed under the same license as the PACKAGE package. #翻译zh_CN.po里对应的字符串为中文:
# Chinese translations for PACKAGE package # PACKAGE 软件包的简体中文翻译. # Copyright (C) 2009 THE PACKAGE'S COPYRIGHT HOLDER # This file is distributed under the same license as the PACKAGE package. #根据po文件生成mo文件。
msgfmt zh_CN.po -o zh_CN.mo
运行该命令后,我们发现,在当前目录下,产生了一个名zh_CN.mo的文件。它是二进制的,不能用文本编辑器打开。
安装mo文件到特定目录中:
cp -f zh_CN.mo .local/LC_MESSAGES/home.mo
修改程序。
setlocale(LC_ALL, 'zh_CN'); // Specify location of translation tables bindtextdomain("home", "."); // Choose domain textdomain("home"); // Translation is looking for in ./locale/zh_CN/LC_MESSAGES/home.mo now $str = gettext('home'); //也可以使用_('home') print {$str} HTML;运行这个脚本, 看看, 是不是输出正确的中文了呢?
添加其它语言也很容易,不需要修改程序,只需要像对待中文一样,生成一个mo文件,并安装到系统中对应的目录即可。切换不同的语言仅仅是修改当前的locale就行了。

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. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. 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,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
