Is there anything in PHP that's like Cookiecontainer in ASP.

Is there anything in PHP that is equivalent to Cookiecontainer in ASP.
In ASP. NET, the access page can be completed by the following function, PostData is the data that requires the post-specified URL:

public string gethtml (string url, Cookiecontainer cookie, byte[] postdata);



How is it implemented in PHP? Is it possible to write like this?

 
  function gethtml ($url, $tmpFile, $postData)
{
$ch = Curl_init ($url);
curl_setopt ($ch, curlopt_header,0);
curl_setopt ($ch, Curlopt_returntransfer, 1);  
curl_setopt ($ch, Curlopt_cookiejar, $tmpFile);

if ($postData!=null)
{
curl_setopt ($ch, Curlopt_post, 1);  

}
$content =curl_exec ($ch);  

return $content;
}
?>

are the following two sentences not few?
curl_setopt ($ch, Curlopt_cookiejar, $tmpFile);
curl_setopt ($ch, Curlopt_cookiefile, $tmpFile);

can I only pass temporary files? Is there any other way to improve it? O (∩_∩) o Thank you, ~~~~~~.

Save to file is the default action
You can use your own function to handle the curlopt_readfunction by setting the
