How to check PCNTL module exists

Question

I write simple requirements checking script. It checks all required PHP modules installed. I need to check if pcntl is installed. But this module is accessible only in cgi environment and invisible for web queries. extension_loaded('pcntl') and function_exists('pcntl_fork') both return false. How can I perform this check?

Answer 1

Running php -i | grep pcntl will return the following if pcntl is enabled.

pcntl

pcntl support => enabled
