Защищенные свойства (Protected)

Свойство	Тип	Описание
$distance		How far to search for a match (0 = exact location, 1000+ = broad match). A match this many characters away from the expected location will add 1.0 to the score (0.0 is a perfect match).
$maxBits		The number of bits in an int.
$threshold		At what point is no match declared (0.0 = perfection, 1.0 = very loose).

Описание методов

__construct() публичный Метод

public __construct ( )

alphabet() публичный Метод

Initialise the alphabet for the Bitap algorithm.

public alphabet ( string $pattern ) : array
$pattern	string	The text to encode.
