Network FunctionsПред.
Эти функции всегда доступны.
Для использования этих функций не требуется проведение установки,
поскольку они являются частью ядра PHP.
-Поведение этих функций зависит от установок в php.ini.
Таблица 1. Network Configuration Options
| Name | Default | Changeable | Changelog |
|---|---|---|---|
| define_syslog_variables | "0" | PHP_INI_ALL |
Для подробного описания констант
PHP_INI_*, обратитесь к документации функции ini_set().
Краткое разъяснение конфигурационных
директив.
define_syslog_variables boolean
- 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().
Данное расширение не определяет никакие типы ресурсов.
-Перечисленные ниже константы всегда доступны как часть ядра PHP.
