inotify_init — Initialize an inotify instance
Initialize an inotify instance for use with inotify_add_watch()
A stream resource or FALSE on error.
Пример #1 Example usage of inotify
<?php
// Open an inotify instance
$fd = inotify_init();
// Watch __FILE__ for metadata changes (e.g. mtime)
$watch_descriptor = inotify_add_watch($fd, __FILE__, IN_ATTRIB);
// generate an event
touch(__FILE__);
// Read events
$events = inotify_read($fd);
print_r($events);
// The following methods allows to use inotify functions without blocking on inotify_read():
// - Using stream_select() on $fd:
$read = array($fd);
$write = null;
$except = null;
stream_select($read,$write,$except,0);
// - Using stream_set_blocking() on $fd
stream_set_blocking($fd, 0);
inotify_read($fd); // Does no block, and return false if no events are pending
// - Using inotify_queue_len() to check if event queue is not empty
$queue_len = inotify_queue_len($fd); // If > 0, inotify_read() will not block
// Stop watching __FILE__ for metadata changes
inotify_rm_watch($fd, $watch_descriptor);
// Close the inotify instance
// This may have closed all watches if this was not already done
fclose($fd);
?>
Результатом выполнения данного примера будет что-то подобное:
array(
array(
'wd' => 1, // Equals $watch_descriptor
'mask' => 4, // IN_ATTRIB bit is set
'cookie' => 0, // unique id to connect related events (e.g.
// IN_MOVE_FROM and IN_MOVE_TO events)
'name' => '', // the name of a file (e.g. if we monitored changes
// in a directory)
),
);
