Methods

UnumberToChar()

Converts a UNICODE number to a UTF-8 multibyte character Algorithm based on script found at From: http://czyborra.com/utf/ Unit-tested by Kasper

public UnumberToChar(int $unicodeInteger) : string

The binary representation of the character's integer value is thus simply spread across the bytes and the number of high bits set in the lead byte announces the number of bytes in the multibyte sequence:

bytes | bits | representation
    1 |    7 | 0vvvvvvv
    2 |   11 | 110vvvvv 10vvvvvv
    3 |   16 | 1110vvvv 10vvvvvv 10vvvvvv
    4 |   21 | 11110vvv 10vvvvvv 10vvvvvv 10vvvvvv
    5 |   26 | 111110vv 10vvvvvv 10vvvvvv 10vvvvvv 10vvvvvv
    6 |   31 | 1111110v 10vvvvvv 10vvvvvv 10vvvvvv 10vvvvvv 10vvvvvv
Parameters
$unicodeInteger : int

UNICODE integer

Return values
string —

UTF-8 multibyte character string

utf8_char_mapping()

Maps all characters of a UTF-8 string.

public utf8_char_mapping(string $str) : string
Parameters
$str : string

UTF-8 string

Return values
string

utf8_to_numberarray()

Converts all chars in the input UTF-8 string into integer numbers returned in an array.

public utf8_to_numberarray(string $str) : array<string|int, mixed>

All HTML entities (like & or £ or { or 㽝) will be detected as characters. Also, instead of integer numbers the real UTF-8 char is returned.

Parameters
$str : string

Input string, UTF-8

Return values
array<string|int, mixed> —

Output array with the char numbers

utf8CharToUnumber()

Converts a UTF-8 Multibyte character to a UNICODE number Unit-tested by Kasper

public utf8CharToUnumber(string $str[, bool $hex = false ]) : int
Parameters
$str : string

UTF-8 multibyte character string

$hex : bool = false

If set, then a hex. number is returned.
