What is the difference between PHP execution and php-cgi execution in Apache modules?

Use PHP later, so do not know the previous version in php-cgi mode of implementation;

and has not used FastCGI;

So I want to ask two questions:

(1) What are the differences between PHP execution and php-cgi execution in Apache modules?
I am now local Mac OSX is using module execution:

LoadModule php5_module        modules/libphp5.so

(2) php-cgi If you do not use PHP-FPM or spawn-fcgi implement FastCGI, is there a website in use?

The first time to Sgementfault, thank you for your answer.

Thank @Jex for the

Http://docs.joomla.org/Should_PHP_run_as_a_CGI_script_or_as_an_Apache_module%3F

Completely solve my doubts, thank you;

Do you speak c? If not, you can ignore all my answers below.

If it will. Have you ever developed a website in C language?

If used, that's the difference.

If it is not used, first understand the principle, the basis of the fight. Naturally, the problem is simple.

(PS: In the afternoon in the group asked the CI framework in the CLI mode error of the bit, is it you?) )
