mb_convert_variables

(PHP 4 >= 4.0.6, PHP 5, PHP 7, PHP 8)

mb_convert_variables — Convert character code in variable(s)

Beschreibung

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.

Parameter-Liste

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.

Rückgabewerte

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

Beispiele

?>
