FAM monitors files and directories, notifying interested applications of
changes. More information about FAM is available at
http://oss.sgi.com/projects/fam/.
A PHP script may specify a list of files for FAM to monitor
using the functions provided by this extension.
The FAM process is started when the first connection
from any application to it is opened. It exits after all
connections to it have been closed.
Замечание:
This extension has been moved to the PECL repository and is no longer bundled with
PHP as of PHP 5.1.0.
Замечание: Для Windows-платформ
это расширение недоступно.
This extension uses the functions of the
FAM library, developed by SGI. Therefore you have to download and
install the FAM library.
To use PHP's FAM support you must compile PHP --with-fam[=DIR] where DIR is the
location of the directory containing the lib and include
directories.
