Answer 1

You are probably thinking about the Asterisk Gateway Interface ( http://www.voip-info.org/wiki/view/Asterisk+AGI+php ) but what you intend to do is best achieved trhough the "originate" action of the Manager interface. Take a look to the PHP examples in voip-info.org: http://www.voip-info.org/wiki/view/Asterisk+manager+Examples

Answer 2

You could also use Call Files if you want to generate outgoing calls from an external application.

If you do this, make sure you mv files into the spool directory, don't use cp!
