preprocessing a php file within another.

Hi folks, I have a problem. I have a file (say 01.php) which has some variables set from a posted form in html. I now need to process another file (say 02.php), which is a html file with php script embeded in it. The processing should take place within 01.php. Not only that, the processing of 02.php should be done with the environment of 01.php ( I need the form variables in 02.php). Can anyone please tell me how to do it. I am listing the methods I have tried. 1. 01.php on preprocessing produces a html file which has javascript with the statement window.location = "02.php". [ unfortunately this won't work because 02.php isn't publicly accessable ] 2. using the system("php 02.php"); statement. [ I don't know how I can transfer the environment variables ] 3. using the file (reads file into an array of strings), implode (combines array of strings into a single string) and eval (evaluates the php string in the current environment) functions. [ unfortunately the eval function requires the whole string to be a php script, but 02.php is essentially a html file with embeded php ] Any suggestions to overcome the problems in any of the above methods, or a new method that might work is welcome. thanks -deepak
