title: Twitter api giving blank response if tweet starts wil @username
body: <p>I am using <a href="https://github.com/J7mbo/twitter-api-php" rel="nofollow">twitter-api-php</a>. I am posting statuses and it works well. The only problem is, when the tweet starts with @username, its returning a blank page. I don't know whats wrong. This problem is not just with me, when googling about it, found another person with same query, </p>
  
  <p>Here is the code I am using to post.</p>
  
  <pre><code>$settings = array(
      'oauth_access_token' =&gt; "ACCESS_TOKEN",
      'oauth_access_token_secret' =&gt; "ACCESS_TOKEN_SECRET",
      'consumer_key' =&gt; CONSUMER_KEY,
      'consumer_secret' =&gt; CONSUMER_SECRET
  );
  
  $url = "https://api.twitter.com/1.1/statuses/update.json";
  $str = "@sourabh_bajaj this is a sample tweet";
  $requestMethod = 'POST';
  
  $twitter=new TwitterAPIExchange($settings);
  echo $twitter-&gt;setPostfields(
      array(
          "trim_user" =&gt; 1,
          "status" =&gt; $str
      )
  )-&gt;buildOauth($url, $requestMethod)-&gt;performRequest();
  </code></pre>
  
  <p>This works well if we remove @sourabh_bajaj from the start of the message. </p>
