<?php
function BSD_Syslog($msg,$severity=7, $program="php-test",$remote_ip='127.0.0.1',$remote_port=514){
  date_default_timezone_set('Asia/Taipei');
  $facility=5;
  $severity=7;
  $PRI = $facility*8+$severity;
  $HEADER=date('M d H:i:s ') . $program;
  $syslog_message = "<{$PRI}>{$HEADER} {$msg}";
  $sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
  socket_sendto($sock, $syslog_message, strlen($syslog_message), 0, $remote_ip, (int)$remote_port);
  socket_close($sock);
}
BSD_Syslog("test: ".rand()%10000);
