Для использования этих функций не требуется проведение установки, поскольку они являются частью ядра PHP.
Поведение этих функций находится в зависимости от установок в 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().
