一.问答题
1.curl_setopt中超时设置,URL设置,post数据接收设置,解压缩设置,HEADER信息设置的参数名分别是什么？
2.curl批量设置参数的函数是什么？
二.编程题
1.封装一个curl类，提供get,post方法,通过传递url,data数据获取某个网址的内容，方法返回信息格式为array('response'=>'网页内容','status'=>'http请求状态码','error'=>'错误信息')
要求能够改header信息,并且有超时机制,zip解压缩功能
一.问答题
1.CURLOPT_TIMEOUT,CURLOPT_URL,CURLOPT_POSTFILEDS,CURLOPT_ENCODING,CURLOPT_HTTPHEADER
2.curl_setopt_array($ch,$options);
