我建议您不要真正依赖数据库进行翻译，这可能确实是一个麻烦的任务，并且在数据编码的情况下可能是一个极端的问题。
前段时间我遇到了类似的问题，并写了下课来解决我的问题

用法
<?php
## /locale/en.php
return array(
'name' => 'Hello {a:1}'
'name_full' => 'Hello {a:1} {a:2}'
);
$locale = new Locale(__DIR__ . '/locale');
$locale->setLocale('en');// load en.php from locale dir
//want to work with auto detection comment $locale->setLocale('en');
echo $locale->translate('name', 'Foo');
echo $locale->translate('name', 'Foo', 'Bar');
这个怎么运作
{a:1}被传递给方法的第一个参数替换被传递给方法Locale::translate('key_name','arg1')
{a:2}的第二个参数替换Locale::translate('key_name','arg1','arg2')
检测如何工作
- 默认情况下，如果
geoip已安装，则它将返回国家/地区代码；geoip_country_code_by_name如果未安装geoip ，则返回到HTTP_ACCEPT_LANGUAGE标头
