Is there a more efficient way to merge values from a row and column of a Sudoku array in PHP, without using a for loop?

To merge values from a row and column of a Sudoku array in PHP without using a for loop, you can use array_map along with array_merge to combine the values from the row and column arrays. This approach eliminates the need for explicit loops and simplifies the code. 

// Sample Sudoku array
$sudoku = [
    [1, 2, 3],
    [4, 5, 6],
    [7, 8, 9]
];

// Get values from the first row and first column
$row = $sudoku[0];
$column = array_column($sudoku, 0);

// Merge values from the row and column arrays
$result = array_merge($row, $column);

print_r($result);
