Deze functies zijn beschikbaar als onderdeel van de standaard module die altijd beschikbaar is.
Er zijn geen handelingen nodig m.b.t. tot installatie voor deze functies, deze maken deel uit van de kern van PHP.
Het gedrag van deze functies wordt beïnvloed vanuit php.ini.

Here's a short explanation of the configuration directives.
define_syslog_variables
booleanWhether 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().
This extension defines a file pointer resource returned by fsockopen() and pfsockopen().
