apache_child_terminate Terminate apache process after this request boolapache_child_terminate apache_child_terminate will register the Apache process executing the current PHP request for termination once execution of PHP code it is completed. It may be used to terminate a process after a script with high memory consumption has been run as memory will usually only be freed internally but not given back to the operating system. The availability of this feature is controlled by the &php.ini; directive child_terminate, which is set to off by default. This feature is also not available on multithreaded versions of apache like the win32 version. See also exit.
