$sClientIp = 'client_ip';
$iErrorKey = 1000;
$oSeasLog = new SeasLog();
var_dump($oSeasLog->setRequestVariable(SEASLOG_REQUEST_VARIABLE_DOMAIN_PORT, $sDomainPort));
var_dump($oSeasLog->setRequestVariable(SEASLOG_REQUEST_VARIABLE_REQUEST_URI, $sRequestUri));
var_dump($oSeasLog->setRequestVariable(SEASLOG_REQUEST_VARIABLE_REQUEST_METHOD, $sRequestMethod));
var_dump($oSeasLog->setRequestVariable(SEASLOG_REQUEST_VARIABLE_CLIENT_IP, $sClientIp));
var_dump($oSeasLog->setRequestVariable($iErrorKey,NULL));
var_dump($oSeasLog->getRequestVariable(SEASLOG_REQUEST_VARIABLE_DOMAIN_PORT) == $sDomainPort);
var_dump($oSeasLog->getRequestVariable(SEASLOG_REQUEST_VARIABLE_REQUEST_URI) == $sRequestUri);
var_dump($oSeasLog->getRequestVariable(SEASLOG_REQUEST_VARIABLE_REQUEST_METHOD) == $sRequestMethod);
var_dump($oSeasLog->getRequestVariable(SEASLOG_REQUEST_VARIABLE_CLIENT_IP) == $sClientIp);
var_dump($oSeasLog->getRequestVariable($iErrorKey));
