在PHP中实现多语言的最佳方法 [英] Best way to implement multilanguage in PHP

问题描述

我有30多种语言的多语言PHP系统.每个定义都是通过define()进行的:

I have multilanguage PHP system with over 30 languages. Each definition is made with define():

define('LN_loader_alt', 'Loading...');

有超过400个定义.

我进行了一些比较，并创建了具有400多个常量的抽象类Lang，这些常量当然代替了define()，例如:

I made a little comparison and created abstract class Lang with over 400 constants and these constant are instead of define() of course, example:

abstract class Lang{
    const LN_loader_alt = 'Loading';
    ...
}

接下来，我需要两个文件，并从Lang类调用了1 define和1 const.接下来，我使用webgrind进行了分析，结果令我惊讶:

Next I required both files and called 1 define and 1 const from class Lang. Next I made analysis with webgrind and results surprised for me:

1)要求具有400个define()的文件执行脚本的时间超过了70％ 2)使用带有常量的抽象类比define()快得多

1) requiring file with 400 defines() took over 70% times of executing script 2) Using abstract class with constant is much faster than define()

我想与您分享这个分析并询问您:将我的系统从"define()"多语言重写为具有常量的抽象类"是最佳且明智的做法吗?也许有任何不利之处?

I'd like to share with You this analysis and ask You: is it optimal and smart to rewrite my system from "define()" multilanguage to "abstract class with constant" multilanguage? Or maybe has it any disadvantages?

推荐答案

我自发地猜测是define()是具有一定开销的运行时函数调用，但是在编译时会解析类定义及其常量.因此有所不同.

My spontaneous guess would be that define() is a runtime function call with a certain overhead, but a class definition and its constants are parsed at compile time. Hence the difference.

话虽如此，这两种解决方案都很糟糕. I18n 是一个已解决的问题，无需再次提出. i18n中最大的问题是工作流程，您需要支持该工作流程的工具.该工作流程是:

Having said that, both solutions are terrible. I18n is a solved problem that does not need to be reinvented yet again. The biggest problem in i18n is the workflow, and you need tools that support that workflow. That workflow is:

• 源中可翻译字符串的标记
• 将所述字符串提取为源代码中性格式
• 将这些字符串翻译成各种语言
• 上述所有内容都是异步的，并且由不同的人员进行并行更改，并保持所有语言之间的所有同步

已经有一些工具可以完成所有这些工作，其中最成熟的一个是gettext.使用它(或类似的东西)，不要使用常量.

There are tools that already do all this, the most established one being gettext. Use it (or something similar), don't use constants.
