    Number of characters in a string

    How can I count the number of characters in a UTF-8 encoded string with PHP version 3.23.58?

    I am using strlen(), with a converted string using utf8_decode(). Always supposing that this function converts unknown characters as single quotation marks '?'. This is enough for counting characters purpose.

    However, is there a more appropiate method?

    PHP Code:
        $string 'six@lgfhfget@;][';
        
    $string_count strlen(ereg_replace('[^[:alpha:]]+'''$string));
        echo 
    $string_count

    Thank you, but is not working.

    It returns 0 length for UTF-8 entries like this: 後味 (it should return 2)

    Have a read of some of the comments here where they discuss the strlen function and UTF-8

    first of all you need to decode the UTF 8 encoded string using utf8_decode() and then use strlen() because UTF8 encoded may have more than one byte in one symbol.

    your php code will be like this :

    echo strlen(utf8_decode($string));
