Properties

$alchars

Array of AL characters

protected array<string|int, mixed> $alchars = array()

$newchardata

Array of processed chars

protected array<string|int, mixed> $newchardata = array()

$numalchars

Number of AL characters

protected int $numalchars = 0

$seq

Sequence to process and return

protected array<string|int, mixed> $seq = array()

Methods

__construct()

Shaping Cursively connected scripts, such as Arabic or Syriac, require the selection of positional character shapes that depend on adjacent characters.

public __construct(array<string|int, mixed> $seq) : mixed

Shaping is logically applied after the Bidirectional Algorithm is used and is limited to characters within the same directional run.

Parameters
$seq : array<string|int, mixed>

isolated Sequence array

Return values
mixed

getSequence()

Returns the processed sequence

public getSequence() : array<string|int, mixed>
Return values
array<string|int, mixed>

combineShadda()

Combine characters that can occur with Arabic Shadda (0651 HEX, 1617 DEC).

protected combineShadda() : mixed

Putting the combining mark and shadda in the same glyph allows to avoid the two marks overlapping each other in an illegible manner.

Return values
mixed

bool

hasPrevChar()

Check previous char

protected hasPrevChar(int|false $prevchar, int $thischar) : bool
Parameters
$prevchar : int|false

Previous char

$thischar : int

Current char

Return values
bool

isFinalChar()

Parameters
$prevchar : int|false

Previous char

$thischar : int

Current char

$nextchar : int|false

Next char

Return values
bool

isLaaLetter()

Check if it is a LAA LETTER

protected isLaaLetter(mixed $prevchar, mixed $thischar) : bool
Parameters
$prevchar : mixed
