我有一个左右wp_nav_menu 在前端显示为一个无序列表：

<nav>
  <ul>
    <?php
      // Left menu
      wp_nav_menu( array(
        \'theme_location\'  => \'left\',
        \'container\' => false,
        \'menu_class\' => false,
        \'items_wrap\' => \'%3$s\' // Removes <ul> and wraps <li>
      ) );
      // Right menu
      wp_nav_menu( array(
        \'theme_location\'  => \'right\',
        \'container\' => false,
        \'menu_class\' => false,
        \'items_wrap\' => \'%3$s\' // Removes <ul> and wraps <li>
      ) );
    ?>
  </ul>
</nav>

在这里重复代码时，我创建了一个名为$menu, 像这样：

<nav>
  <ul>
    <?php
      // Left
      $menu = array(\'container\' => false, \'menu_class\' => false, \'items_wrap\' => \'%3$s\');
      wp_nav_menu( array(
        \'theme_location\'  => \'left\',
        $menu
      ) );
      // Right
      wp_nav_menu( array(
        \'theme_location\'  => \'right\',
        $menu
      ) );
    ?>
  </ul>
</nav>

这是在数组中调用变量的正确方法还是有更有效的方法？

array(
    \'theme_location\'  => \'right\',
    array(
        \'container\' => false,
        \'menu_class\' => false,
        \'items_wrap\' => \'%3$s\' // Removes <ul> and wraps <li>
    ),
)

// Left
$menu = array(\'container\' => false, \'menu_class\' => false, \'items_wrap\' => \'%3$s\');
wp_nav_menu( array_merge( 
    array( \'theme_location\'  => \'left\' ),
    $menu
) );
// Right
wp_nav_menu( array_merge( 
    array( \'theme_location\'  => \'right\' ),
    $menu
) );
