php 中unlink和@unlink?
看到有的PHP用 unlink删除文件 ,有的用@unlink删除文件?
这2个的区别是什么?

有时用unlink而用@unlink不可以.

------解决方案--------------------
只是控制有没输出错误

有时用unlink而用@unlink不可以.

你确认是这样？你的不可以是怎么判断的
------解决方案--------------------
有时用unlink而用@unlink不可以.
报什么错了吗？
------解决方案--------------------
有时用unlink而用@unlink不可以
正好相反！应该是
有时用@unlink而用unlink不可以

你再仔细看看？！

@ 屏蔽掉错误输出

当删除一个不存在或只读的文件时，是要报错的
@ 作用就是：错了也不告诉你！骗你没商量

------解决方案--------------------
删除文件出错是很正常的事情,比如安全软件扫描文件的时候很容易因为被占用删除不了,
所以1次删除不了是很正常的.

但是一定要有对策,比如删除失败重试3次,如果3次还删除不了那可能就有问题了.
