windows下php-cgi进程守护

php在linux,unix下有php-fpm,spawn-fcgi等进程守护程序,但是在window下没有。 一般会以下命令启动C:/php5/php-cgi.exe-b127.0.0.1:9000-cC:/php5/php.ini 但是这样受限于php-cgi的PHP_FCGI_MAX_REQUESTS环境变量，默认处理500次后自动退出php-cgi.加之一些非

php在linux,unix下有php-fpm,spawn-fcgi等进程守护程序,但是在window下没有。
一般会以下命令启动 C:/php5/php-cgi.exe -b 127.0.0.1:9000 -c C:/php5/php.ini
但是这样受限于php-cgi的PHP_FCGI_MAX_REQUESTS环境变量，默认处理500次后自动退出php-cgi.加之一些非正常原因的异常退出，都会导致php-cgi.exe的退出。所有在window需要进程守护程序，当php-cgi退出后自动打开新的php-cgi进程。
注意事项：windows建议关闭Dr. Watson，否则 异常的php-cgi无法正常退出。
