difference between executing curl_close() once or frequently?

Question

When is it necessary to close curl connection and release resources consumed by it?

Why do I ask this question, well quite simply because I was told, that PHP garbag

Answer 1

Depends. In my case since I was initializing curl instance in my custom CurlClient constructor

$this->ch = curl_init();

And then using same $curlClient object for multiple api calls, closing the instance

curl_close($this->ch);

would affect other API calls. Methods using the same object will not work, so I'm not closing it.
