[PHP] PECL Inotify Masks Mapped

The PHP documentation for PECL Inotify is very cryptic when you just want to know the equivalent integer value for each constant. So I mapped the inotify integer masks for myself and everyone else (see below). Might save you save you some time. I will be posting soon a very useful application of inotify which can really power up your PHP-based CLI apps. Cheers!

php > echo IN_ACCESS; //File was accessed (read) (*)
1
php > echo IN_MODIFY; //File was modified (*)
2
php > echo IN_ATTRIB; //Metadata changed (e.g. permissions, mtime, etc.) (*)
4
php > echo IN_CLOSE_WRITE; //File opened for writing was closed (*)
8
php > echo IN_OPEN; //File not opened for writing was closed (*)
32
php > echo IN_MOVED_TO; //File was opened (*)
128
php > echo IN_MOVED_FROM; //File moved into watched directory (*)
64
php > echo IN_CREATE; //File or directory created in watched directory (*)
256
php > echo IN_DELETE; //File or directory deleted in watched directory (*)
512javascript:void(0)
php > echo IN_DELETE_SELF; //Watched file or directory was deleted
1024
php > echo IN_MOVE_SELF; //Watch file or directory was moved
2048
php > echo IN_CLOSE; //Equals to IN_CLOSE_WRITE | IN_CLOSE_NOWRITE
24
php > echo IN_MOVE; //Equals to IN_MOVED_FROM | IN_MOVED_TO
192
php > echo IN_ALL_EVENTS; //Bitmask of all the above constants
4095
php > echo IN_UNMOUNT; //File system containing watched object was unmounted
8192
php > echo IN_Q_OVERFLOW; //Watch was removed (explicitly by inotify_rm_watch() or because file was removed or filesystem unmounted
16384
php > echo IN_ISDIR; //Subject of this event is a directory
1073741824
php > echo IN_ONLYDIR; //Only watch pathname if it is a directory (Since Linux 2.6.15)
16777216
php > echo IN_DONT_FOLLOW; //Do not dereference pathname if it is a symlink (Since Linux 2.6.15)
33554432
php > echo IN_MASK_ADD; //Add events to watch mask for this pathname if it already exists (instead of replacing mask).
536870912
php > echo IN_ONESHOT; //Monitor pathname for one event, then remove from watch list.
