	      Using syslog(3)

	      <?php
	      // open syslog, include the process ID and also send
	      // the log to standard error, and use a user defined
	      // logging mechanism
	      openlog("myScriptLog", LOG_PID | LOG_PERROR, LOG_LOCAL0);

	      // some code

	      if (authorized_client()) {
		  // do something
	      } else {
		  // unauthorized client!
		  // log the attempt
		  $access = date("Y/m/d H:i:s");
		  syslog(LOG_WARNING, "Unauthorized client: $access {$_SERVER['REMOTE_ADDR']} ({$_SERVER['HTTP_USER_AGENT']})");
	      }

	      closelog();
	      ?>
