If you are looking for a way to close the handle and write out the cookie file before script execution ends you can use:
unset($ch);
(PHP 4 >= 4.0.2, PHP 5, PHP 7, PHP 8)
curl_close — Close a cURL session
Note:
This function has no effect. Prior to PHP 8.0.0, this function was used to close the resource.
Closes a cURL session and frees all resources. The cURL handle,
handle, is also deleted.
No value is returned.
| Version | Description |
|---|---|
| 8.0.0 |
handle expects a CurlHandle
instance now; previously, a resource was expected.

Example #1 Initializing a new cURL session and fetching a web page
<?php
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
?>
If you are looking for a way to close the handle and write out the cookie file before script execution ends you can use:
unset($ch);Although the Note for this call says "Prior to PHP 8.0.0, this function was used to close the resource", I found that PHP 7.4.33 on CentOS is not closing the connection on curl_close.
The workaround if you want to make sure the connection closes immediately after the request is to set the curl option to forbid reuse:
curl_setopt($curl, CURLOPT_FORBID_REUSE, TRUE);
