Metóda - mb_strlen

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

The mb_strlen() function (as multi-byte string length) gets the length of a string (i.e. the number of characters). It replaces the old strlen() function that returned the number of characters of the string in ASCII encoding and it did not support special characters in UTF-8 encoding.

Procedurálne

• function mb_strlen (string $str, string $encoding = mb_internal_encoding()) : mixed
