如何使用PHP从tumblr帖子获取标签和日期？(How to get tags and the date from tumblr posts using php?)

我是PHP的新手，我设法在我的网站上获得tumblr帖子。但只有标题和身体。

1.）为什么我不能抓住约会？ 2.）如何浏览所有标签并将其导出？

这是我的代码：

<?php ini_set('display_errors', true); error_reporting(-1); $request_url = 'http://cedricfjacob.tumblr.com/api/read?type=post&start=0&num=10'; $xml = simplexml_load_file($request_url); $posts = $xml->xpath("/tumblr/posts/post"); foreach($posts as $post) { $title = $post->{'regular-title'}; $post = $post->{'regular-body'}; $tag = $post->{'tag'}; $date = $post['date']; echo '<div class="title">'.$title.'</div>'; echo '<div class="date">'.$date.'</div>'; echo '<div class="tags">'.$tag.'</div>'; echo '<div class="post">'.$post.'</div>'; }?>

要查看XML，请访问：

感谢你们。

I am rather new to PHP and I managed to get tumblr posts on my website. But only the title and the body.

1.) Why is it that I cannot grab the date? 2.) How do I go through all the tags and export them as well?

Here is my code:

<?php ini_set('display_errors', true); error_reporting(-1); $request_url = 'http://cedricfjacob.tumblr.com/api/read?type=post&start=0&num=10'; $xml = simplexml_load_file($request_url); $posts = $xml->xpath("/tumblr/posts/post"); foreach($posts as $post) { $title = $post->{'regular-title'}; $post = $post->{'regular-body'}; $tag = $post->{'tag'}; $date = $post['date']; echo '<div class="title">'.$title.'</div>'; echo '<div class="date">'.$date.'</div>'; echo '<div class="tags">'.$tag.'</div>'; echo '<div class="post">'.$post.'</div>'; }?>

Thank you guys.

最满意答案

这是因为两个原因：

使用$post = $post->{'regular-body'}; 你写了 $post值。它不再是你所期望的。

第二个 - 属性$post['date']是一个SimpleXMLElement对象。要获取它的字符串值 - 例如使用strval或使用(string)类型转换。

到底：

foreach($posts as $post) { $title = $post->{'regular-title'}; $post_body = $post->{'regular-body'}; // change here $tag = $post->{'tag'}; $date = strval($post['date']); // change here echo '<div class="title">'.$title.'</div>'; echo '<div class="date">'.$date.'</div>'; echo '<div class="tags">'.$tag.'</div>'; echo '<div class="post">'.$post_body.'</div>'; // change here }

This happens because of two reasons:

With $post = $post->{'regular-body'}; you ovewrite $post value. It is no longer what you expect.

Second - attribute $post['date'] is a SimpleXMLElement object. To get string value of it - use strval for example or (string) typecasting.

In the end:

foreach($posts as $post) { $title = $post->{'regular-title'}; $post_body = $post->{'regular-body'}; // change here $tag = $post->{'tag'}; $date = strval($post['date']); // change here echo '<div class="title">'.$title.'</div>'; echo '<div class="date">'.$date.'</div>'; echo '<div class="tags">'.$tag.'</div>'; echo '<div class="post">'.$post_body.'</div>'; // change here }
