/**

* In this example, six non-blocking HTTP/1 requests are made by enabling option "SWOOLE_HOOK_CURL" for the curl

* extension.

* Each request takes about two seconds to finish; however, since the requests are made in non-blocking mode, it takes

* barely over two seconds to finish all the requests.

*

* Notes:

* * This feature works under Swoole 4.4.0+.

* * This approach doesn't work for curl_multi_* functions. To hook curl_multi_* functions, please check the other

* example in file "./hooks/native-curl.php".

*

* How to run this script:

* docker compose exec -t client bash -c "./hooks/curl.php"

*

* You can run following command to see how much time it takes to run the script:

* docker compose exec -t client bash -c "time ./hooks/curl.php"
