PHP CURL模拟GET及POST函数代码

PHP CURL模拟GET及POST函数代码，需要的朋友可以参考下。

代码如下:
function vcurl($url, $post = '', $cookie = '', $cookiejar = '', $referer = ''){
$tmpInfo = '';
$cookiepath = getcwd().'./'.$cookiejar;
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
if($referer) {
curl_setopt($curl, CURLOPT_REFERER, $referer);
} else {
curl_setopt($curl, CURLOPT_AUTOREFERER, 1);
}
if($post) {
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $post);
}
if($cookie) {
curl_setopt($curl, CURLOPT_COOKIE, $cookie);
}
if($cookiejar) {
curl_setopt($curl, CURLOPT_COOKIEJAR, $cookiepath);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookiepath);
}
//curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl, CURLOPT_TIMEOUT, 100);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$tmpInfo = curl_exec($curl);
if (curl_errno($curl)) {
echo '

错误:
'.curl_error($curl); 
} 
curl_close($curl); 
return $tmpInfo; 
} 
?>
