How to make PHP permanently running script "forget" everything and perform almost as a restart

Question

I have a PHP script running permanently on a server. I have very limited access to restart it. Is there any way how to reset everything in the script from inside? I do not mean to physically stop and start the script.

I'm looking for a way how to almost restart it (unset() all variables, un include all includes, "forgot" all functions) almost like a restart of the script.

The reason is to be able to "update" the script at least during the debugging phase. On a local host everything works as it supposed, but on a server there are some issues and for any change I have to call to a service desk). Lets say to make some changes in the include - then include it again, that means to initialize new functions, activate new variables....

I know that restart would be easier, nicer, crone would do the job, but unfortunately there is not the option... (Stupid situation, I know - but I can not change it, so looking for solution within my reach)

The idea is

<?
while (true) {
  require(myInclude.php);

  while (true){
    // here is the code I need to process, it is in endless loop as it serves as a websocket server
    doWhatIsNeeded(this_works_fine_no_need_to_adjust);

    // condition that starts all the "cleaning"
    if ($restartIsRequired == true){
      break;
    }
  }
  //unset all variables, un include all includes, "forget" all functions

It depends on what you are trying to do with your function, I would need more info to try and help more. It seems like you could benefit from using a scheduler such as a cron job.
