mb_convert_variables — Convert character code in variable(s)
$to_encoding,$from_encoding,&$var,&...$vars
Converts
character encoding of variables var and vars in
encoding from_encoding to encoding
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.
to_encodingThe encoding that the string is being converted to.
from_encoding
The current encoding of the variables. Multiple encodings may be
specified as an array or comma separated string,
in which case the encoding is detected among the listed encodings.
"auto" is expanded according to the
mbstring.language INI setting.
var
var 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
Additional vars.
The character encoding before conversion for success,
or false for failure.
