php - 使用 PHP 和新的 Twitter API

Question

由于新的 Twitter API，我使用 PHP 在我的网页上使用 PHP 显示 1 条最新推文。

目前我已经让它工作了，所以推文只是作为一个简单的文本字符串输出。我的问题是如何控制输出的 HTML？如果在推文中声明了主题标签或网址，我希望能够将链接显示为链接。我该怎么做？

到目前为止，这是我的代码，它在我的页面中将字符串输出为推文:

function get_tweet() {

require 'tmhOAuth.php';
require 'tmhUtilities.php';

$tmhOAuth = new tmhOAuth(array(
'consumer_key' => 'secret',
'consumer_secret' => 'secret',
'user_token' => 'secret',
'user_secret' => 'secret',
'curl_ssl_verifypeer' => false
));

$code = $tmhOAuth->request('GET', $tmhOAuth->url('1.1/statuses/user_timeline'), array(
'screen_name' => 'evanrichards',
'count' => '1'));

$response = $tmhOAuth->response['response'];
$tweets = json_decode($response, true);
echo($tweets[0]['text']);

}

Answer 1

这是一些用 php 中的链接替换链接、主题标签和 attags 的示例代码

$tweet = "@george check out http://www.google.co.uk #google";

//Convert urls to <a> links
$tweet = preg_replace("/([\w]+\:\/\/[\w-?&;#~=\.\/\@]+[\w\/])/", "<a target=\"_blank\" href=\"$1\">$1</a>", $tweet);

//Convert hashtags to twitter searches in <a> links
$tweet = preg_replace("/#([A-Za-z0-9\/\.]*)/", "<a target=\"_new\" href=\"http://twitter.com/search?q=$1\">#$1</a>", $tweet);

//Convert attags to twitter profiles in <a> links
$tweet = preg_replace("/@([A-Za-z0-9\/\.]*)/", "<a href=\"http://www.twitter.com/$1\">@$1</a>", $tweet);

echo $tweet;

这给出了输出

<a href="http://www.twitter.com/george">@george</a> check out <a target="_blank" href="http://www.google.co.uk">http://www.google.co.uk</a> <a target="_new" href="http://twitter.com/search?q=google">#google</a>

因此您可以将代码更改为

function get_tweet() {

  require 'tmhOAuth.php';
  require 'tmhUtilities.php';

  $tmhOAuth = new tmhOAuth(array(
  'consumer_key' => 'secret',
  'consumer_secret' => 'secret',
  'user_token' => 'secret',
  'user_secret' => 'secret',
  'curl_ssl_verifypeer' => false
  ));

  $code = $tmhOAuth->request('GET', $tmhOAuth->url('1.1/statuses/user_timeline'), array(
  'screen_name' => 'evanrichards',
  'count' => '1'));

  $response = $tmhOAuth->response['response'];
  $tweets = json_decode($response, true);

  $tweet = $tweets[0]['text'];
  $tweet = preg_replace("/([\w]+\:\/\/[\w-?&;#~=\.\/\@]+[\w\/])/", "<a target=\"_blank\" href=\"$1\">$1</a>", $tweet);
  $tweet = preg_replace("/#([A-Za-z0-9\/\.]*)/", "<a target=\"_new\" href=\"http://twitter.com/search?q=$1\">#$1</a>", $tweet);
  $tweet = preg_replace("/@([A-Za-z0-9\/\.]*)/", "<a href=\"http://www.twitter.com/$1\">@$1</a>", $tweet);
  echo($tweet);

}

我确信正则表达式可以改进。

或者更好的是，您可以将其拆分为它自己的函数。

function linkify_tweet($tweet) {

  $tweet = preg_replace("/([\w]+\:\/\/[\w-?&;#~=\.\/\@]+[\w\/])/", "<a target=\"_blank\" href=\"$1\">$1</a>", $tweet);
  $tweet = preg_replace("/#([A-Za-z0-9\/\.]*)/", "<a target=\"_new\" href=\"http://twitter.com/search?q=$1\">#$1</a>", $tweet);
  $tweet = preg_replace("/@([A-Za-z0-9\/\.]*)/", "<a href=\"http://www.twitter.com/$1\">@$1</a>", $tweet);

  return $tweet;

}

function get_tweet() {

  require 'tmhOAuth.php';
  require 'tmhUtilities.php';

  $tmhOAuth = new tmhOAuth(array(
  'consumer_key' => 'secret',
  'consumer_secret' => 'secret',
  'user_token' => 'secret',
  'user_secret' => 'secret',
  'curl_ssl_verifypeer' => false
  ));

  $code = $tmhOAuth->request('GET', $tmhOAuth->url('1.1/statuses/user_timeline'), array(
  'screen_name' => 'evanrichards',
  'count' => '1'));

  $response = $tmhOAuth->response['response'];
  $tweets = json_decode($response, true);

  echo(linkify_tweet($tweets[0]['text']));

}
