Just a quick note, FileSystemWatcher in .NET is actually not recommended for
use by Microsoft.
It does not guarantee that an event will be raised on every new file or file
mod in a given folder… and it's even less determinstic when trying to deal with
network share drives.
Microsoft's own developer blogs usually recommend that people roll their own
polling-based solution instead of depending on FileSystemWatcher (googling
FileSystemWatcher will yield many many results regarding this).
I'm not necessarily saying that the overall idea is without merit… but it's
just that if someone does want to try and implement something like this on
Windows, they should try and avoid whatever Win32 API calls that
FileSystemWatcher uses.
Ok, thank you for the note. I didn't look deeply in Windows API, just
Mac OS X and Linux for the moment… Thank you again.

Hi internal,
A missing feature in PHP is a file system watcher/monitoring available for
almost all platforms. On Linux, we have inotify (available in PHP through
pecl/inotify), on Mac OS X, we have /dev/fsevents (not available in PHP, since
we need ioctl to do that in pure PHP —and sudo—, no C extension needed), on
FreeBSD, we have FAM, and on Windows, we have FileSystemWatcher in .NET. All
major platforms have a solution ready to use.
By now, if we didn't use these solutions, we should use a finder (thanks to
RecursiveIteratorIterator and DirectoryIterator in SPL) that runs every n
seconds and compute a diff with the previous run. This solution works fine for
a small set of files but it can slow for a big one. This is just a tricky
solution, not a proper one.
Possible domains where it is needed: test, CI, log, file transfering, security
etc.
Is it possible to have such a feature landing in PHP (core if karma allows it)?
or do you want such a feature?
Best regards :-).
