Just because your PHP script is executed by the AGI dialplan application 
does not make it an AGI.

Your script does not follow the AGI protocol. It does not read the AGI 
environment, it executes no AGI requests, and it reads no AGI responses.

You should do some reading on what an AGI is. 
http://www.voip-info.org/wiki/view/Asterisk+AGI would be a good start.

2 (biased) suggestions:

1) Use an established AGI library. Nobody gets it right the first time.

2) Consider using a compiled language like C. You can execute xxx's of 
AGIs written in C in the time it takes to load PHP and parse your script.
