[Asterisk-Users] AGI questions..

[WipeOut]

Hi,

First off, can AGI scripts be created using PHP??.. This is where our 
skills are and since PHP can be run from a command line it would be 
easier to create and maintain..

I understand that AGI works using STDIN and STDOUT, so does that mean 
that I would simply "echo" the standard Asterisk commands that I wanted 
Asterisk to execute and it would process them?

Are any call variables passed to the AGI script on execution? Where can 
I get a list of these?

Finally, If I execute a call from within an AGI script, will the script 
continue processing when the call is hung up or terminated or would I 
have to use another AGI on the "h" extension to process post call 
operations?

Thanks for your help..
