php里有无异于Asp.Net中 CookieContainer的东西吗

<br /><?php<br />function getHtml($url,$tmpFile,$postData)<br />{<br />	$ch = curl_init($url);<br />	curl_setopt($ch,CURLOPT_HEADER,0);<br />	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);  <br />	curl_setopt($ch, CURLOPT_COOKIEJAR, $tmpFile);<br />	curl_setopt($ch, CURLOPT_COOKIEFILE, $tmpFile); <br />	if($postData!=NULL)<br />	{<br />		curl_setopt($ch, CURLOPT_POST, 1);  <br />		curl_setopt($ch, CURLOPT_POSTFIELDS, $postData); <br />	}<br />	$content=curl_exec($ch);  <br />	curl_close($ch); <br />	return $content;<br />}<br />?>
