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.

int|false $nextchar)
: bool
Parameters
- $thischar : int
-
Current char
- $nextchar : int|false
-

int $thischar)
: bool
Parameters
- $prevchar : int|false
-
Previous char
- $thischar : int
-

int|false $nextchar)
: bool
Parameters
- $prevchar : int|false
-
Previous char
- $thischar : int
-
Current char
- $nextchar : int|false
-

Return values
bool —isLaaLetter()
Check if it is a LAA LETTER
protected isLaaLetter(mixed $prevchar,
mixed $thischar)
: bool
Parameters
