mb_convert_variablesConvert character code in variable(s)

Descrição

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.

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.

Parâmetros

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.

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.

...

Additional vars.

Valor Retornado

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