wikipedia api: get parsed introduction only

我已经到了维基百科文章的第一部分。但第一部分包括图片以及文字。我想要的只是文字。这是我的cURL回复中输出的html

   Some of the many different games known as football.

  <p>The game of <b>football</b> is any of several similar <a href="/wiki/Team_sport"  title="Team sport">team sports</a>, of similar origins which involve advancing a ball into   a goal area in an attempt to score. Many of these involve <a href="/wiki/Kick_(football)"  title="Kick (football)">kicking</a> a ball with the foot to score a <a  href="/wiki/Goal_(sport)" title="Goal (sport)">goal</a>, though not all codes of football  using kicking as a primary means of advancing the ball or scoring. The most popular of these sports worldwide is <a href="/wiki/Association_football">association football</a>,   more commonly known as just "football" or "soccer". Unqualified, the word <i><a  href="/wiki/Football_(word)" title="Football (word)">football</a></i> applies to whichever  form of football is the most popular in the regional context in which the word appears,  including <a href="/wiki/American_football">American football</a>, <a href="/wiki/Australian_rules_football">Australian rules football</a>, <a  href="/wiki/Canadian_football">Canadian football</a>, <a  href="/wiki/Gaelic_football">Gaelic football</a>, <a href="/wiki/Rugby_league">rugby  league</a>, <a href="/wiki/Rugby_union">rugby union</a> and other related games.

我真正想要的代码是否位于段落标签中，如果有用的话？（从单词 - “游戏”开始

我在网址中抓取数据的网址就是这个 -

 'http://en.wikipedia.org/w/api.php?action=parse&page='.$search.'&redirects=1&format=json&prop=text&section=0'

我尝试过的示例代码 -

 <?php

 include_once('simple_html_dom.php');

 $html = file_get_html('http://amazon.co.uk/');

 foreach($html->find('p') as $element)   
 {
 echo $element->plaintext . '<br>';
 }

 ?>

遗憾的是，这会返回一个空白页

Answer 1

只需下载Simple HTML DOM parser

即可

然后使用它：

include_once('simple_html_dom.php');

$html = file_get_html('http://en.wikipedia.org/wiki/Football');

foreach($html->find('p') as $element)   
{
    echo $element->plaintext . '<br>';
    break;
}
