1.fopen方式

//访问指定URL函数function access_url($url) {        if ($url=='') return false;        $fp = fopen($url, 'r') or exit('Open url faild!');        if($fp){      while(!feof($fp)) {            $file.=fgets($fp)."";      }      fclose($fp);        }      return $file;  }

2.file_get_contents方式(打开远程文件的时候会造成CPU飙升。file_get_contents其实也可以post)

$content = file_get_contents("http://www.google.com");

3.curl方式

function curl_file_get_contents($durl){      $ch = curl_init();      curl_setopt($ch, CURLOPT_URL, $durl);      curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ; // 获取数据返回        curl_setopt($ch, CURLOPT_BINARYTRANSFER, true) ; // 在启用 CURLOPT_RETURNTRANSFER 时候将获取数据返回        $r = curl_exec($ch);      curl_close($ch);      return $r;  }

4.fsockopen方式(只能获取网站主页信息,其他页面不可以)

$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);     if (!$fp) {         echo "$errstr ($errno)<br />\n";     } else {         $out="GET / HTTP/1.1\r\n";         $out.="Host: www.example.com\r\n";         $out.="Connection: Close\r\n\r\n";         fwrite($fp, $out);         while (!feof($fp)) {             echo fgets($fp, 128);         }      fclose($fp);     }

  1. I’m really enjoying the theme/design of your website.
    Do you ever run into any browser compatibility issues? A handful of my blog visitors have complained about my site not working correctly
    in Explorer but looks great in Chrome. Do you have any tips to help fix this issue?

  2. I like what you guys are usually up too. This type of clever work and coverage!
    Keep up the fantastic works guys I’ve incorporated
    you guys to my personal blogroll.

  3. Hi there! I know this is kinda off topic nevertheless I’d figured I’d ask.
    Would you be interested in trading links or maybe guest writing a blog post or vice-versa?
    My website covers a lot of the same topics as yours and
    I feel we could greatly benefit from each other. If you’re
    interested feel free to shoot me an e-mail.

    I look forward to hearing from you! Superb blog by the way!

  4. Greetings! Very helpful advice in this particular post!
    It’s the little changes which will make the largest changes.

  5. At worst, they could end up with a product containing harmful ingredients, as has happened with many of the fake versions of Viagra that have been sold around the world

  6. Please let me know if you’re looking for a article author
    for your blog. You have some really good posts and I believe I would be a good
    asset. If you ever want to take some of the load off, I’d absolutely love
    to write some material for your blog in exchange for a link back to mine.
    Please blast me an email if interested. Thank you!
