Fill your data as each line is a row of your solved sudoku

$sudokuArray = [
[1, 8, 2, 5, 4, 3, 6, 9, 7],
[9, 6, 5, 1, 7, 8, 3, 4, 2],
[7, 4, 3, 9, 6, 2, 8, 1, 5],
[3, 7, 4, 8, 9, 6, 5, 2, 1],
[6, 2, 8, 4, 5, 1, 7, 3, 9],
[5, 1, 9, 2, 3, 7, 4, 6, 8],
[2, 9, 7, 6, 8, 4, 1, 5, 3],
[4, 3, 1, 7, 2, 5, 9, 8, 6],
[8, 5, 6, 3, 1, 9, 2, 7, 4],
];

Then make an instance of the Factory of this package and build the Sudoku entity as below :

$factory =  new  Factory();

$sudoku =  new  Sudoku($factory);
$sudoku->build($sudokuArray);

And finally validate that solved sudoku is correct or not!

$sudokuValidator =  new  Validator();

if ($sudokuValidator->validate($sudoku)) {
echo  "true \n";
} else {
echo  "false \n";
}
