PHP中使用gettext来支持多语言的方法
网学网为需要PHP的朋友们搜集整理了PHP中使用gettext来支持多语言的方法相关资料，希望对各位网友有所帮助!
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:
复制代码 代码如下:
//home.php:
$str = ''home'';
print <<<HTML
<a href="#">{$str}</a>
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：
复制代码 代码如下:
# 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 <EMAIL@ADDRESS>, YEAR.
#
#, fuzzy
msgid ""
msgstr ""
"Project-Id-Version: PACKAGE VERSION\n"
"Report-Msgid-Bugs-To: \n"
"POT-Creation-Date: 2009-07-23 20:56+0800\n"
"PO-Revision-Date: YEAR-MO-DA HO:MI+ZONE\n"
"Last-Translator: FULL NAME <EMAIL@ADDRESS>\n"
"Language-Team: LANGUAGE <LL@li.org>\n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=CHARSET\n"
"Content-Transfer-Encoding: 8bit\n"
#: home.php:2
msgid "home"
msgstr "
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：
复制代码 代码如下:
# 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.
# <huixinchen@localhost.localdomain>, 2009.

msgid ""
msgstr ""
"Project-Id-Version: PACKAGE VERSION\n"
"Report-Msgid-Bugs-To: \n"
"POT-Creation-Date: 2009-07-23 20:56+0800\n"
"PO-Revision-Date: 2009-07-23 21:00+0800\n"
"Last-Translator: FULL NAME <EMAIL@ADDRESS>\n"
"Language-Team: Chinese\n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=GB2312\n"
"Content-Transfer-Encoding: 8bit\n"
#: test.php:2
msgid "home"
msgstr "
翻译zh_CN.po里对应的字符串为中文：
复制代码 代码如下:
# 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.
# <huixinchen@localhost.localdomain>, 2009.
