1.file_get_contents
php代码
- <?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;
- ?>
2.curl
PHP代码
- <?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;
- ?>
3.fopen->fread->fclose
PHP代码
- <?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;
- ?>
Ps1.使用file_get_contents和fopen必须空间开启allow_url_fopen。方法：编辑php.ini，设置allow_url_fopen = On，allow_url_fopen关闭时fopen和file_get_contents都不能打开远程文件。
Ps2.使用curl必须空间开启curl。方法：WIN下修改php.ini，将extension=php_curl.dll前面的分号去掉，而且需要拷贝ssleay32.dll和libeay32.dll到C:\WINDOWS\system32下；Linux下要安装curl扩展。
