方法一：file_get_contents 函数
example：
<?php $url = "http://www.cnblogs.com"; $contents = file_get_contents($url); echo $contents; ?>
出现乱码需要在输出前加一句：
$getcontent = iconv("gb2312", "utf-8",$contents);
方法二：fopen
example：
<?php $handle = fopen ("http://www.cnblogs.com", "rb"); $contents = ""; do { $data = fread($handle, 1024); if (strlen($data) == 0) { break; } $contents .= $data; } while(true); fclose ($handle); echo $contents; ?>
但是方法一和方法二需要服务器中php的配置开启了“allow_url_fopen = On”，才允许远端访问
方法三：curl（这种方法比较好用。）
