PHP中获取远程文件的三种方法

<?php 
  $url = 'http://www.xxx.com/';
  $contents = file_get_contents($url);
  //如果出现中文乱码使用下面代码
  //$getcontent = iconv(“gb2312″, “utf-8″,file_get_contents($url));
  //echo $getcontent;
  echo $contents;
?>

<?php
    url = “http://www.xxx.com/”;
    $ch = curl_init();
    $timeout = 5;
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);//在需要用户检测的网页里需要增加下面两行
    //curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
    //curl_setopt($ch, CURLOPT_USERPWD, US_NAME.”:”.US_PWD);
    $contents = curl_exec($ch);
    curl_close($ch);
    echo $contents;
?>

<?php
  $handle = fopen (“http://www.xxx.com/”, “rb”);
  $contents = “”;
  do {
    $data = fread($handle, 8192);
      if (strlen($data) == 0){
        break;
      }
      $contents .= $data;
    } while(true);
    fclose ($handle);
  echo $contents; 
?>
