分享下页面关键字抓取www.icbase.com站点代码(带asp.net参数的)

代码如下:/**

//set_time_limit(0);
// base function
function curl_get($url,$data = array(),$header = array(),$timeout = 15,$port = 80,$reffer = '',$proxy = '')

$result['result'] = curl_exec($ch);
if (0 != curl_errno($ch)) {
$result['error'] = "Error:n" . curl_error($ch);}
curl_close($ch);
return $result;
}

代码如下:function curl_post($url,$timeout = 5,$port = 80)
