定义和用法

setlocale() 函数设置区域设置信息。

区域设置信息是特定于地理区域的语言、货币、时间和其他信息。

笔记：setlocale() 函数仅更改当前脚本的区域设置。

提示：可以使用 setlocale(LC_ALL,NULL) 将语言环境信息设置为系统默认值

提示：要获取数字格式信息，请参阅语言环境转换()功能。

语法

setlocale( constant,location)

参数值

Parameter	Description
constant	Required. Specifies what locale information should be set. Available constants: LC_ALL - All of the below LC_COLLATE - Sort order LC_CTYPE - Character classification and conversion (e.g. all characters should be lower or upper-case) LC_MESSAGES - System message formatting LC_MONETARY - Monetary/currency formatting LC_NUMERIC - Numeric formatting LC_TIME - Date and time formatting
location	Required. Specifies what country/region to set the locale information to. Can be a string or an array. It is possible to pass multiple locations. If the location is NULL or the empty string "", the location names will be set from the values of environment variables with the same names as the constants above, or from "LANG". If the location is "0", the location setting is not affected, only the current setting is returned. If the location is an array, setlocale() will try each array element until it finds a valid language or region code. This is very useful if a region is known under different names on different systems. Note: To view all available language codes, go to our Language code reference.
