mb_convert_variables

(PHP 4 >= 4.0.6, PHP 5, PHP 7)

mb_convert_variables — Convert character code in variable(s)

Description

mb_convert_variables ( string $to_encoding , array|string $from_encoding , mixed &$var , mixed &...$vars ) : string|false

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.

Parameters

to_encoding

The encoding that the string is being converted to.

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.

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.

Return Values

The character encoding before conversion for success, or false for failure.
