我只是想通过帖子ID获取WordPress内容.我发现以下三种通过帖子ID获取WordPress内容的方法.(我在该网站上找到的以下所有方法.)

方法01:

 $content_post = get_post($my_postid);
$content = $content_post->post_content;
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]&gt;', $content);

方法02:

 $content=get_post_field('post_content', $my_postid);

方法03:

 $content=apply_filters('the_content', get_post_field('post_content', $my_postid));

什么是最好的/最有效的方法?为什么?

I just wanted to get WordPress content by post id. I found the following three ways to get WordPress content by post id. (All the following ways I found on this site.)

Method 01:

$content_post = get_post($my_postid);
$content = $content_post->post_content;
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]&gt;', $content);

Method 02:

$content=get_post_field('post_content', $my_postid);

Method 03:

$content=apply_filters('the_content', get_post_field('post_content', $my_postid));

What is the best / efficient way from above there methods and why?

- 我想说的是代码,函数调用和查询最少的方法.您做了什么来尝试剖析这些内容?您的基准测试结果如何?您是否在内容中加入了oEmbeds和Shortcode,这有关系吗?收集数据后,您将在哪里使用这些数据?您应该为问题提供更好的背景,以获得更有用的答案.
  
  I'd say the way with the least amount of code, function calls, and queries. What did you do to try and profile these? What are the results of your benchmarks? Did you account for oEmbeds and Shortcode in your content - does that matter? Where are you using this data after you gather it? You should supply better context to the question for a more useful answer.

- 另外,我想我还记得有一些要在内容上运行的过滤器-http://wordpress.stackexchange.com/a/245057/84219
  
  Also, I think I remember there being a few filters to run on the content - http://wordpress.stackexchange.com/a/245057/84219

- 正如@jgraup所说,这个问题缺乏上下文,"最佳"只能在特定上下文中针对不平凡的任何事物来决定
  
  as @jgraup say, this question lacks context and "best" can be decided only in a specific context for anything which is not trivial

您提供的用于比较的方法几乎相同,只是API稍有不同,并且是否应用了the_content过滤器.

通常应在循环中使用get_the_content(),该代码可以正确处理拆分为页面等内容.

要检索原始内容,通常使用get_post_field(),但是任何进一步的处理(例如the_content过滤器)在很大程度上取决于特定的目的检索内容以及您将如何处理它.

PS请注意,许多扩展很笨拙,并且在循环外执行的the_content过滤器上多次中断.
