PHP使用cURL模拟登陆，采集信息

这是一个函数，还能够在精炼，如下是代码

<?php
  //var_dump($_SERVER);exit;
  $cookie_file = tempnam('./temp','cookie');  //建立cookie文件保存的位置
  //echo $cookie_file;exit;
 function  curl($url,$data=array(),$method,$setcooke=false,$cookie_file=false){
		$ch = curl_init();	 //1.初始化
		curl_setopt($ch, CURLOPT_URL, $url); //2.请求地址
		curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);//3.请求方式
		//4.参数以下	禁止服务器端的验证
		curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
		curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
		//假装请求来源，绕过防盗
	   //curl_setopt($ch,CURLOPT_REFERER,"http://wthrcdn.etouch.cn/");
	   //配置curl解压缩方式（默认的压缩方式）
	   curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept-Encoding:gzip'));
       curl_setopt($ch, CURLOPT_ENCODING, "gzip");

		curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0'); //指明以哪一种方式进行访问
		curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
		curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
		if($method=="POST"){//5.post方式的时候添加数据	
			curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
		}
		if($setcooke==true){
			 //若是设置要请求的cookie，那么把cookie值保存在指定的文件中
			curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);
		}else{
			 //就从文件中读取cookie的信息
			curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
		}
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
		$tmpInfo = curl_exec($ch);

		if (curl_errno($ch)) {
			return curl_error($ch);
		}
		curl_close($ch);
		return $tmpInfo;
	}
