cli_set_process_title() - Sets the process title
pcntl_fork() - 在当前进程当前位置产生分支（子进程）。译注：fork是创建了一个子进程，父进程和子进程都从fork的位置开始向下继续执行，不同的是父进程执行过程中，得到的fork返回值为子进程号，而子进程得到的是0。

You should use cli_set_process_title() ( http://php.net/manual/en/function.cli-set-process-title.php ) instead; it's less dangerous and less buggy, and part of PHP itself as of 5.5.

Note that this extension is considered buggy.  See https://wiki.php.net/rfc/cli_process_title, which says:

"...but it is incomplete and might lead to memory corruption on Linux (or any OS which does not support setproctitle.

The reason is the extension only has access to original argv[0] (that comes from main()). argv and environ(7) are in contiguous memory space on Linux. The extension presumes that argv[0] can accomodate 128 characters, but usually that is not possible because argv[0] is “php”. When this happens, the extension will scribble on argv[1], argv[2], etc., and maybe even environ and this can have destructive side effects on the running program."
