mb_convert_variables — Convert character code in variable(s)

### Description

string mb_convert_variables ( string `$to_encoding` , mixed `$from_encoding` , mixed `&$vars` [, mixed `&$...` ] )

mb_convert_variables() convert character encoding of variables `vars` in encoding `from_encoding` to encoding `to_encoding` . It returns character encoding before conversion for success, `FALSE` for failure.

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.

It `from_encoding` is specified by array or comma separated string, it tries to detect encoding from `from-coding` . When `encoding` is omitted, detect_order is used.

`vars (3rd and larger)` is reference to variable to be converted. String, Array and Object are accepted. mb_convert_variables() assumes all parameters have the same encoding.

Example#1 mb_convert_variables() example

`<?php
/* Convert variables $post1, $post2 to internal encoding */
$interenc = mb_internal_encoding();
$inputenc = mb_convert_variables($interenc, "ASCII,UTF-8,SJIS-win", $post1, $post2);
?>`
