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.
Note: This extension has been moved to the » PECL repository and is no longer bundled with PHP as of PHP 5.1.0.
Note: Esta extensión no está disponible en plataformas Windows
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.
Esta extensión no tiene directivas de configuración en php.ini.
There are two resource types used in the FAM module. The first one is the connection to the FAM service returned by fam_open(), the second a monitoring resource returned by the fam_monitor_XXX functions.
