Multi-line function definition not indented correctly

[ghost]

Hello,

Being relatively new with this I hope it would be OK to ask in perhaps not that many technical terms.

I was wondering on how to write this snippet best:

add_action( 'init', 'create_secondary_taxonomies' );
function create_secondary_taxonomies() {
  $labels = array(
    'name' => _x( 'Mogelijkheden', 'taxonomy general name' ),
    'singular_name' => _x( 'Mogelijkheid', 'taxonomy singular name' ),
  );
  register_taxonomy(
    'mogelijkheid',
    array( 'product' ),
    array(
      'labels' => $labels,
      'hierarchical' => true,
      'query_var' => true,
      'rewrite' => array(
        'hierarchical' => true,
        'slug' => 'mogelijkheid',
        'with_front' => false,
      ),
      'public' => true,
      'show_ui' => true,
    )
  );
}

as I'm currently receiving this error:

FOUND 3 ERROR(S) AFFECTING 3 LINE(S)
--------------------------------------------------------------------------------
  9 | ERROR | Multi-line function definition not indented correctly; expected 6
    |       | spaces but found 4 (WordPress.Functions.FunctionCallSignature)

 11 | ERROR | Multi-line function definition not indented correctly; expected 6
    |       | spaces but found 4 (WordPress.Functions.FunctionCallSignature)

I can understand why 4 spaces, but I'm somewhat lost on why 6.

I can reproduce, however WP coding standard is to use tabs for indentation at the beginning of the line and it's encompassed in larger "Line is indented with space, not tab" issue. Reformatting to the standard with tabs makes it go away together with spaces.

If using tabs fixes the issue, then this is the fix 😄
