mb_convert_variables
- (PHP 4 >= 4.0.6, PHP 5, PHP 7)
- mb_convert_variables — Convert character code in variable(s)
- mb_convert_variables — 转换一个或多个变量的字符编码
Description
string mb_convert_variables ( string $to_encoding , mixed $from_encoding , mixed &$vars [, mixed &$... ] )
//Converts character encoding of variables vars in encoding from_encoding to encoding to_encoding.
//将变量 vars 的编码从 from_encoding 转换成编码 to_encoding。
//mb_convert_variables() join strings in Array or Object to detect encoding, since encoding detection tends to fail for short strings. Therefore, it is impossible to mix encoding in single array or object.
//mb_convert_variables() 会拼接变量数组或对象中的字符串来检测编码，因为短字符串的检测往往会失败。因此，不能在一个数组或对象中混合使用编码。
Parameters
to_encoding
- The encoding that the string is being converted to.
- 将 string 转换成这个编码。
from_encoding
- from_encoding is specified as an array or comma separated string, it tries to detect encoding from from-coding. When from_encoding is omitted, detect_order is used.
- from_encoding 可以指定为一个 array 或者逗号分隔的 string，它将尝试根据 from-coding 来检测编码。 当省略了 from_encoding，将使用 detect_order。
vars
- vars is the reference to the variable being converted. String, Array and Object are accepted. mb_convert_variables() assumes all parameters have the same encoding.
- vars 是要转换的变量的引用。 参数可以接受 String、Array 和 Object 的类型。 mb_convert_variables() 假设所有的参数都具有同样的编码。
...
- Additional vars.
- 额外的 vars。
Return Values
- The character encoding before conversion for success, or FALSE for failure.
- 成功时返回转换前的字符编码，失败时返回 FALSE。
