How do I find out the version of HTTP in a request using PHP and Apache

Question

I need to determine whether an HTTP request was an HTTP/1.0 or an HTTP/1.1 request in my PHP script, which is running under Apache. Is there a way to query this information?

$_SERVER['SERVER_PROTOCOL'] as at $_SERVER^Docs:

'SERVER_PROTOCOL'
Name and revision of the information protocol via which the page was requested; i.e. 'HTTP/1.0';
