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.
