计划任务执行php文件问题
写了个a.php文件，
又写了个bat，内容是:
C:\wamp\bin\php\php5.3.8\php.exe -f E:\photoselect\work\a.php
在任务计划里定时执行bat，设置5分钟执行一次
但经常5分钟是处理不完的，会在5分钟后又跑了一个bat，这样会出错，
（在计划任务里已经设置了到时未运行完成，不起新实例），但貌似无效，不知道这是不是仅针对exe的
请各位帮忙，谢谢
------解决方案--------------------
5分钟处理不完，只能想办法提高a.php的效率了，查查瓶颈在哪里，考虑多线程。
另外未完成不起新实例，是针对bat的，php里你需要自己实现重复进程检测。
------解决方案--------------------
修改a.php的文件 运行的时候判断是否还有在运行，是的话直接退出.不是的话运行结束销毁标志
