Do zbudowania tego rozszerzenia nie są wymagane żadne zewnętrzne biblioteki.
By używać tych funkcji, nie trzeba niczego instalować. Są one częścią jądra PHP.
Na działanie tych funcji wpływają ustawienia zawarte w pliku php.ini.
Tabela 1. Network Configuration Options
Name | Default | Changeable | Changelog |
---|---|---|---|
define_syslog_variables | "0" | PHP_INI_ALL |
Oto krótkie wyjaśnienie dyrektyw konfiguracji.
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().
To rozszerzenie nie posiada żadnych rodzajów zasobów.
Poniższe stałe są częścią jądra PHP a więc są zawsze widoczne.
