LXVII. Network Functions

Introduction

Requirements

   No external libraries are needed to build this extension.

Installation

   There is no installation needed to use these functions; they are part
   of the PHP core.

Runtime Configuration

   The behaviour of these functions is affected by settings in php.ini.

   Table 1. Network Configuration Options
   Name                    Default Changeable
   define_syslog_variables "0"     PHP_INI_ALL
   For further details and definition of the PHP_INI_* constants see
   ini_set().

   Here's a short explanation of the configuration directives.

   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().

Resource Types

   This extension has no resource types defined.

Predefined Constants

   The constants below are always available as part of the PHP core.

   Table 2. openlog() Options
   Constant Description
   LOG_CONS if there is an error while sending data to the system logger,
   write directly to the system console
   LOG_NDELAY open the connection to the logger immediately
   LOG_ODELAY (default) delay opening the connection until the first
   message is logged
   LOG_NOWAIT
   LOG_PERROR print log message also to standard error
   LOG_PID include PID with each message

   Table 3. openlog() Facilities
   Constant Description
   LOG_AUTH security/authorization messages (use LOG_AUTHPRIV instead in
   systems where that constant is defined)
   LOG_AUTHPRIV security/authorization messages (private)
   LOG_CRON clock daemon (cron and at)
   LOG_DAEMON other system daemons
   LOG_KERN kernel messages
   LOG_LOCAL0 ... LOG_LOCAL7 reserved for local use, these are not
   available in Windows
   LOG_LPR line printer subsystem
   LOG_MAIL mail subsystem
   LOG_NEWS USENET news subsystem
   LOG_SYSLOG messages generated internally by syslogd
   LOG_USER generic user-level messages
   LOG_UUCP UUCP subsystem

   Table 4. syslog() Priorities (in descending order)
   Constant    Description
   LOG_EMERG   system is unusable
   LOG_ALERT   action must be taken immediately
   LOG_CRIT    critical conditions
   LOG_ERR     error conditions
   LOG_WARNING warning conditions
   LOG_NOTICE  normal, but significant, condition
   LOG_INFO    informational message
   LOG_DEBUG   debug-level message

   Table 5. dns_get_record() Options
   Constant Description
   DNS_A IPv4 Address Resource
   DNS_MX Mail Exchanger Resource
   DNS_CNAME Alias (Canonical Name) Resource
   DNS_NS Authoritative Name Server Resource
   DNS_PTR Pointer Resource
   DNS_HINFO Host Info Resource (See IANA's Operating System Names for
   the meaning of these values)
   DNS_SOA Start of Authority Resource
   DNS_TXT Text Resource
   DNS_ANY Any Resource Record. On most systems this returns all resource
   records, however it should not be counted upon for critical uses. Try
   DNS_ALL instead.
   DNS_AAAA IPv6 Address Resource
   DNS_ALL Iteratively query the name server for each available record
   type.
