Il n'y pas d'installation nécessaire pour utiliser ces fonctions, elles font parties du coeur de PHP.
Le comportement de ces fonctions est affecté par la configuration dans le fichier php.ini.
For further details and definition of the PHP_INI_* constants see ini_set().
Here is a short explanation of the configuration directives.
Whether or not to define the various syslog variables (e.g. $LOG_PID, $LOG_CRON, etc.). Turning it off is a good idea performance-wise. At runtime, you can define these variables by calling define_syslog_variables().
Les constantes listées ici sont toujours disponibles dans PHP.
