Sure.  php code is just text, and you can write text to a file in most 
computer programming languages.  Here is a ruby example:

File.open("prog1.php", "w") do |file|
  file.puts("<?php echo 'hello' ?>")
end

I think you should be able to execute a php script doing something like 
this:

system("path1 path2")

where path1 is the path to php and path2 is the path to prog1.php.
