How to stop PHP code execution

Question

Is there a way to immediately stop PHP code execution   I am aware of exit but it clearly states      Terminates execution of the script  Shutdown functions and object destructors will always be executed even if exit is called         So what I want to achieve is to stop the PHP code execution exactly when I call exit or whatever   Any help   Edit  After Jenson s answer  Trial 1   function newExit           halt compiler          echo  start   newExit        echo  you should not see this     Shows Fatal error    HALT COMPILER   can only be used from the outermost scope in which was pretty expected   Trial 2   function newExit         include  e php     echo  start   newExit    echo  you should not see this     e php just contains   halt compiler     This shows startyou should not see this  Edit  Why I want to do this   I am working on an application that includes a proprietary library  required through virtual host config file to which I don t have access  that comes as encrypted code  Is a sort of monitoring library for security purpose  One of it s behaviours is that it registers some shutdown functions that log the instance status  it saves stats to a database   What I want to do is to disable this logging for some specific conditions based on  remote IP

Please see the following information from user Pekka    According to the manual  destructors are executed even if the script gets terminated using die   or exit      The destructor will be called even if script execution is stopped using exit    Calling exit   in a destructor will prevent the remaining shutdown routines from executing   According to this PHP  destructor vs register shutdown function  the destructor does not get executed when PHP s execution time limit is reached  Confirmed on Apache 2  PHP 5 2 on Windows 7    The destructor also does not get executed when the script terminates because the memory limit was reached   Just tested   The destructor does get executed on fatal errors  Just tested  Update  The OP can t confirm this - there seem to be fatal errors where things are different  It does not get executed on parse errors  because the whole script won t be interpreted   The destructor will certainly not be executed if the server process crashes or some other exception out of PHP s control occurs   Referenced in this question Are there any instances when the destructor in PHP is NOT called

I m not sure you understand what  exit  states  Terminates execution of the script  Shutdown functions and object destructors will always be executed even if exit is called    It s normal to do that  it must clear it s memmory of all the variables and functions you called before  Not doing this would mean your memmory would remain stuck and ocuppied in your RAM  and if this would happen several times you would need to reboot and flush your RAM in order to have any left
