Te funkcije so na voljo znotraj standardnega modula, ki je vedno na voljo.
Te funkcije ne potrebujejo namestitve, saj so del jedra PHP.
The behaviour of these functions is affected by settings in php.ini.
For further details and definition of the PHP_INI_* constants see ini_set().
Here's 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().
Ta razširitev ne določa nobenega tipa sredstev.
Navedene konstante so vedno na voljo kot del jedra PHP.
