采集微博的PHP代码

     PHP采集腾讯微博只留文字部分.    <pre class="brush:php; toolbar: true; auto-links: false;"><?php header("Content-type:text/html;charset=utf-8"); $weibo = file_get_contents('http://t.qq.com/starank');  $preg = '/<div class="msgCnt">(.*)<\/div><div class="mediaWrap">/Uis'; preg_match_all($preg, $weibo, $string);  foreach ($string[1] as $key=>$value){  echo delhtml($value)."<br/><br/><br/>"; }  function delhtml($str) // 清除HTML标签 {  $st = -1; //开始  $et = -1; //结束  $stmp = array();  $stmp[] = "&nbsp;";  $len = strlen($str);  for($i = 0;$i < $len;$i++)  {   $ss = substr($str, $i, 1);   if (ord($ss) == 60) // ord("<")==60   {    $st = $i;   }   if (ord($ss) == 62) // ord(">")==62   {    $et = $i;    if ($st != -1)    {     $stmp[] = substr($str, $st, $et - $st + 1);    }   }  }  $str = str_replace($stmp, "", $str);  return $str; }  ?></pre>
