如何从缓存中排除一页？

Question

我有生成随机数的php代码（用于数组）。这仅适用于Dev，不适用于暂存。我的猜测是因为缓存。有没有办法关闭此1页的缓存？

<?php
      $rand = mt_rand(0,4);

      $video_list = ['video_url', 'video_2_url', 'video_3_url', 'video_4_url', 'video_5_url'];
      $image_list = ["image", "image2", "image3", "image4", "image5"];
      $video_url = $video_list[$rand];
      $image_url = $image_list[$rand];

      $tile_data = array(
        "color_scheme" => get_sub_field('color_scheme'),
        "image_url" => get_sub_field($image_url),
        "image_alt" => get_sub_field('title'),
        "video_url" => get_sub_field($video_url),
        "right_content" => get_sub_field('right_content'),
      );
    ?>
