Help on loading variables from one swf to another swf via php

Guys
This question might be a common one …I too have googled for it a lot but cudnt find the solution for my problem.

I have a swf file that loads variable into a php file by :

my_lv.send("file.php","_blank","POST");

php then uses these variables.

I have embedded a second swf file inside this php file( php coding between html tags ) . How can I make this second swf file load these variables that were passed from the first swf file ??
Lets say the my_lv had 3 values of variables my_lv.1=1 ,my_lv.2=2 , my_lv.3=3 . They are present inside the file.php as $1 , $2 and $3 .
How can i load just the $3 to the second swf ???

I hope my question is clear .

Really look forwards to help from experts as always.
Thanks in anticipation …
