C. Network Functions
Wymagania
Do zbudowania tego rozszerzenia nie są wymagane żadne zewnętrzne biblioteki.
Instalacja
By używać tych funkcji, nie trzeba niczego instalować. Są one częścią jądra PHP.
Konfiguracja uruchomieniowa
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.
define_syslog_variablesbooleanWhether 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().
Typy zasobów
To rozszerzenie nie posiada żadnych rodzajów zasobów.
Stałe predefiniowane
Poniższe stałe są częścią jądra PHP a więc są zawsze widoczne.
