Call to undefined function curl_init() even it is enabled in php7

The error message "Call to undefined function curl_init()" typically indicates that the cURL extension for PHP is not installed or is not enabled. To resolve this issue, you should check to see if the cURL extension is installed on your server. If it is not installed, you can install it using the package manager for your operating system. If it is installed, you should check to see if it is enabled in your PHP configuration. This can typically be done by checking the output of the phpinfo() function or by looking for the extension in your php.ini file and ensuring that it is not commented out.
