Load php to flash

I have a big problem.
First of all, I have never been educated php and flash but I learn them myself. Now, I have a big problem.

I’m running a php programm and now I want the php program merges the flash program I’m working.

The php file’s name always change. E.g, this.php?id=123123, this.php?id=147147 and so on…
However, I have to load “this.php” into flash. Flash shows different content accoounting different “id”(this.php?id=)
So, I can not just use: mySomething.load(“this.php”);.

What can I do???
