奉献出一个封装的curl函数，便于调用

复制代码 代码如下:

function curl($url, $ifpost = 0, $datafields = '', $cookiefile = '', $v = false) {
$header = array("Connection: Keep-Alive","Accept: text/html, application/xhtml+xml, */*", "Pragma: no-cache", "Accept-Language: zh-Hans-CN,zh-Hans;q=0.8,en-US;q=0.5,en;q=0.3","User-Agent: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)");
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, $v);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
$ifpost && curl_setopt($ch, CURLOPT_POST, $ifpost);
$ifpost && curl_setopt($ch, CURLOPT_POSTFIELDS, $datafields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate');
$cookiefile && curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiefile);
$cookiefile && curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiefile);
$r = curl_exec($ch);
curl_close($ch);
return $r;
}
