body: <p>How can I run several PHP scripts from within another PHP script, like a batch file?  I don't think include will work, if I understand what include is doing; because each of the files I'm running will redeclare some of the same functions, etc.  What I want is to execute each new PHP script like it's in a clean, fresh stack, with no knowledge of the variables, functions, etc. that came before it.</p>
  
  <p><strong>Update</strong>: I should have mentioned that the script is running on Windows, but not on a web server.</p>
