setlocale( constant,location )
| 参数 | 描述 |
|---|---|
| constant | 必需。规定应该设置什么地区信息。 可用的常量：
|
| location | 必需。规定把地区信息设置为什么国家/地区。可以是字符串或者数组。可以传递多个位置。 如果 location 参数是 NULL 或空字符串 ""，则位置名称会被设置为上面常量中同名的环境变量的值或者根据 "LANG" 进行设置。 如果 location 参数是 "0"，则位置设置不受影响，只返回当前的设置。 如果 location 参数是数组，setlocale() 会尝试每个数组元素，直到找到合法的语言或地区代码为止。如果某个地区在不同的系统上拥有不同的名称，这一点很有用。 注释：如需查看所有可用的语言代码，请访问我们的语言代码参考手册 。 |

| Update log: | In PHP 4.2.0, it has been abandoned to the constant passed as a string is deprecated. Please use the constant instead of the available. The constants passed as a string will produce a warning message. In PHP 4.3.0, you can pass multiple locations. Since PHP 5.3.0 onwards, if the parameter is passed to the constant string, rather than one LC_ constants, the function will throw a E_DREPRECATED notice. |
