Question

可能重复:
帮助获取元标题和描述

我花了一整天的时间.在网上搜索.在satckoverflow上也看到了一些类似的问题.但我都失望了.

我想得到一些PHP代码,通过它我可以输出标题和一些4-5行的任何网站的描述使用PHP.

<?php

  $url = "http://www.drquincy.com/";

  $fp = fopen($url, 'r');
  $content = "";
  while(!feof($fp)) {
        $buffer = trim(fgets($fp, 4096));
        $content .= $buffer;
  }


  $start = '<title>';
  $end = '</title>';
  preg_match(" / $start( . * )$end / s", $content, $match);
  $title = $match[1];
  $metatagarray = get_meta_tags($url);
  $keywords = $metatagarray["keywords"];
  $description = $metatagarray["description"];
  echo " <div><strong>URL: </strong >$url</div> \n";
  echo " <div><strong>Title: </strong >$title</div> \n";
  echo " <div><strong>Description: </strong >$description</div>\n";
  echo " <div><strong>Keywords: </strong >$keywords</div>\n";
