### Beschreibung

string mb_strtolower ( string `$str` [, string `$encoding` ] )

Returns `str` with all alphabetic characters converted to lowercase.

### Parameter-Liste

`str`

  The string being lowercased.

`encoding`

  Der `encoding` Parameter legt das Zeichenencoding fest. Wird er nicht übergeben so wird das interne Zeichenencoding genutzt.

### Rückgabewerte

### Unicode

For more information about the Unicode properties, please see » http://www.unicode.org/unicode/reports/tr21/.

By contrast to strtolower(), 'alphabetic' is determined by the Unicode character properties. Thus the behaviour of this function is not affected by locale settings and it can convert any characters that have 'alphabetic' property, such as A-umlaut (Ä).

### Beispiele

`<?php
$str = "Mary Had A Little Lamb and She LOVED It So";
$str = mb_strtolower($str);
echo $str; // Prints mary had a little lamb and she loved it so
?>`
