I suggest you look at https://codex.wordpress.org/Function_Reference/wp_get_post_revisions

<?php
            // Lets get the revisions of the given $post we are accessing by ID ( you are probably going to want to limit your internal revision count for this

            $revisions =  wp_get_post_revisions($post->ID);
            // lets just do some formatting here ( your post html content is going to display normally but lets get the var_dump to look decent
            echo \'<pre>\';
            //  print the $revisions variable to look at the internals
            var_dump($revisions);
            echo \'</pre>\';

            // from here i would dig into iterating over the revisions array.
            ?>

在循环中使用上述代码应该可以开始了解可以从wp\\u get\\u post\\u revisions（）返回什么类型的数据。您需要在post\\u date部分进行一些搜索，或者查看数组键并按整数排序，然后推送到键与count（）匹配的自定义数组，以仅返回最新的post修订。这个查询将是巨大的，所以我真诚地建议您限制wordpress安装版本数。
