Question

这里有类似的问题/答案： Need a good regex to convert URLs to links but leave existing links alone

我已经尝试了几个答案，但没有运气。

我的网站上有一个Twitter Feed轮播。一些推文中有链接。

例如，一条推文是Happy Thanksgiving everyone! https://shortenedURL.com/blahblah。

另一个是Full Schnabel Loaded With Wind Tower Base Section Left Turn: https://shortenedURL.com/blahblah via @YouTube，其中@YouTube已经是一个链接（我猜测Twitter转换了这个链接。

这就是我的尝试：

$tweetText = $tweet->text;
$tweetText = preg_replace('@(?!(?!.*?<a)[^<]*<\/a>)(?:(?:https?|ftp|file)‌://|www\.|ftp\.)[-A-‌Z0-9+&#/%=~_|$?!:,.]‌*[A-Z0-9+&#/%=~_|$]@‌i','<a href="\0" target="_blank">\0</a>', $tweetText);

但没有任何东西在转换。如上所述，我还尝试了上述相关问题中的一些其他示例和答案。

完整代码：

//Path to TwitterOAuth library
require_once("twitter/twitteroauth.php");

//Configuration
$twitterID = (isset($_REQUEST['twitterUsername']) && !empty($_REQUEST['twitterUsername']))?$_REQUEST['twitterUsername']:"username";
$tweetNum = 10;
$consumerKey = "consumerkey";
$consumerSecret = "consumersecret";
$accessToken = "accesstoken";
$accessTokenSecret = "accesstokensecret"; 
if($twitterID && $consumerKey && $consumerSecret && $accessToken && $accessTokenSecret) {
      //Authentication with twitter
      $twitterConnection = new TwitterOAuth(
          $consumerKey,
          $consumerSecret,
          $accessToken,
          $accessTokenSecret
      );
      //Get user timeline feeds
      $twitterData = $twitterConnection->get(
          'statuses/user_timeline',
          array(
              'screen_name'     => $twitterID,
              'count'           => $tweetNum,
              'exclude_replies' => true
          )
      );

    </div>
  </div>
<?php   
}else{
      echo 'Authentication failed, please try again.';
}

我尽我所能，不知道还能做什么。

使用带有获取的Twitter状态的preg_replace
