PHP嵌套'foreach'循环仅使用数组的最后一个值

Question

我编写了以下循环来更快地创建 WordPress 自定义控件：

<?php
  /* Creates "Color Scheme" section */
  $wp_customize->add_panel('color_scheme', array(
    'title' => 'Color Scheme',
    'priority' => 120,
  ));
    /* Creates "Navbar" section */
    $wp_customize->add_section('navbar', array(
      'title'    => 'Navbar',
      'description' => '',
      'priority' => 120,
      'panel' => 'color_scheme'
    ));
      /* Navbar Color Controls */
      $color_controls = array("menu-bg-color", "menu-button-color", "menu-site-title-color", "menu-overlay-bg-color", "menu-items-color");
      $color_labels = array("Background Color", "Button Color", "Title Color", "Overlay Background Color", "Overlay Item Color");
      foreach($color_controls as $control) {
        foreach($color_labels as $label) {
          $wp_customize->add_setting($control);
          $wp_customize->add_control(new WP_Customize_Color_Control($wp_customize, $control, array(
            'label' => $label,
            'section' => 'navbar',
            'settings' => $control
          )));
        }
      }
?>

这是结果：Screenshot of my WordPress customizer 它不循环遍历标签，只使用最后一个值。

$color_controls = array(
  "menu-bg-color" => "Background Color", 
  "menu-button-color" => "Button Color", 
  "menu-site-title-color" => "Title Color", 
  "menu-overlay-bg-color" => "Overlay Background Color", 
  "menu-items-color" => "Overlay Item Color"
);

foreach ($color_controls as $control => $label) {
  $wp_customize->add_setting($control);
  $wp_customize->add_control(new WP_Customize_Color_Control($wp_customize, $control, array(
    'label' => $label,
    'section' => 'navbar',
    'settings' => $control
  )));
}

我认为这就是您要寻找的。嵌套循环适用于当您希望 array2 中的每个项目用于 array1 中的每个项目时。您实际上想要一个键和值的关联数组，并循环遍历它们，其中键是您的控件，映射到您的标签值。
