预定义常量

下列常量由此扩展定义,且仅在此扩展编译入 PHP 或在运行时动态载入时可用。

Inotify 常量可用于 inotify_add_watch() 或由 inotify_read() 返回
IN_ACCESS (int)
文件被访问(读)(*)
IN_MODIFY (int)
文件被修改(*)
IN_ATTRIB (int)
元数据变更(例如:权限、修改时间等)(*)
IN_CLOSE_WRITE (int)
打开写入后关闭的文件(*)
IN_CLOSE_NOWRITE (int)
未打开写入的文件被关闭(*)
IN_OPEN (int)
文件被打开(*)
IN_MOVED_TO (int)
文件被移动到监听目录(*)
IN_MOVED_FROM (int)
文件移出监听目录(*)
IN_CREATE (int)
在监听目录中创建文件或文件夹(*)
IN_DELETE (int)
监听目录中删除文件或文件夹(*)
IN_DELETE_SELF (int)
监听的文件或目录被删除
IN_MOVE_SELF (int)
监听的文件或目录被移动
IN_CLOSE (int)
与 IN_CLOSE_WRITE | IN_CLOSE_NOWRITE 相等
IN_MOVE (int)
与 IN_MOVED_FROM | IN_MOVED_TO 相等
IN_ALL_EVENTS (int)
以上所有常量的位掩码
IN_UNMOUNT (int)
卸载包含监听对象的文件系统
IN_Q_OVERFLOW (int)
事件队列溢出(此事件中监听描述符是 -1)
IN_IGNORED (int)
监听被移除(通过 inotify_rm_watch() 显示移除,或者是文件被移动,或者文件系统被卸载)
IN_ISDIR (int)
事件发生的主体是目录
IN_ONLYDIR (int)
如果是目录,仅监听路径名(从 Linux 2.6.15 开始)
IN_DONT_FOLLOW (int)
如果是符号链接,不引用路径名(从 Linux 2.6.15 开始)
IN_MASK_ADD (int)
如果路径名存在,追加监听此路径的事件掩码(代替更换掩码)
IN_ONESHOT (int)
路径触发一个监听事件后,从监听列表中移除。

注意: 以上标有星号 (*) 的事件可能发生在已监听目录的文件中。

Be carefull using IN_MODIFY :Lot of UNIX editor, for instance like 'vi', work in a 'xxx~' file, and changes are written in 'xxx' when saving or saving and closing.If a watcher is done on 'xxx', no IN_MODIFY event occurs while not saved !Prefere IN_CLOSE_WRITE in such case .

I noticed that the values of the constants seem to be missing. Granted, these could change dependant on version but on my system here are the values (should you want them).IN_ACCESS = 1IN_MODIFY = 2IN_ATTRIB = 4IN_CLOSE_WRITE = 8IN_CLOSE_NOWRITE = 16IN_OPEN = 32IN_MOVED_FROM = 64IN_MOVED_TO = 128IN_CREATE = 256IN_DELETE = 512IN_DELETE_SELF = 1024IN_MOVE_SELF = 2048IN_UNMOUNT = 8192IN_Q_OVERFLOW = 16384IN_IGNORED = 32768IN_CLOSE = 24IN_MOVE = 192IN_ALL_EVENTS = 4095IN_ONLYDIR = 16777216IN_DONT_FOLLOW = 33554432IN_MASK_ADD = 536870912IN_ISDIR = 1073741824IN_ONESHOT = 2147483648
