Using PHP, how do I get the first paragraph of a W

问题:

How do I use PHP to get the first paragraph of any article from Wikipedia through their MediaWiki API?

I am open to all suggestions. Most probably CURL or XML will come in handy.

回答1:

You can use the API as so:

http://en.wikipedia.org/w/api.php?action=parse&page=Stack_overflow&format=xml&prop=text&section=0

This will return an xml file with structure:

<?xml version="1.0"?>
<api>
  <parse title="Article Title">
    <text xml:space="preserve">Text you wanted goes here</text>
  </parse>
</api>

Note the variables: page=Article_Title_Goes_Here format=xml prop=text

I would use file_get_contents('http://wikipedia.com/'.$rest_of_url)

Then just use string parsing to select everything form
