开启CURL扩展，让服务器支持PHP curl函数(远程采集)_PHP
curl()、file_get_contents()、snoopy.class.php这三个远程页面抓取或采集中用到的工具，默迹还是侵向于用snoopy.class.php，因为他效率比较高且不需要服务器特定配置支持，在普通虚拟主机中即可使用，file_get_contents()效率稍低些，常用失败的情况、curl()效率挺高的，支持多线程，不过需要开启下curl扩展。下面是curl扩展开启的步骤：
1、将PHP文件夹下的三个文件php_curl.dll,libeay32.dll,ssleay32.dll复制到system32下;
2、将php.ini(c:WINDOWS目录下)中的;extension=php_curl.dll中的分号去掉;
3、重启apache或者IIS。
