REQUEST_METHOD problem

[Jyotsna]

I don't see what this error:

Notice: Undefined index: REQUEST_METHOD in C:\WebPub[url]www.upt.pt\www\htdocs\pesquisa\libs\utils.php[/url] on line 402

has to do with this line:

$retVal = $GLOBALS[$envVar];

Can anyone help me?

Could you post some more of the surrounding code. I'm finding it difficult to understand the context.
Thanks Rob

this is the complete function:

function getEnvVar($envVar) {
global $config;
global $HTTP_ENV_VARS;
global $HTTP_SERVER_VARS;

if ($config['debug'] > 1) {
	printf("<BR>->Debug: getEnvVar() - getenv(\"%s\"): %s<BR>\n", $envVar, getenv($envVar));
	printf("->Debug: getEnvVar() - \$GLOBALS[\"%s\"]: %s<BR>\n", $envVar, $GLOBALS[$envVar]);
	printf("->Debug: getEnvVar() - \$HTTP_ENV_VAR[\"%s\"]: %s<BR>\n", $envVar, $HTTP_ENV_VARS[$envVar]);
	printf("->Debug: getEnvVar() - \$HTTP_SERVER_VAR[\"%s\"]: %s<BR>\n", $envVar, $HTTP_SERVER_VARS[$envVar]);
}

$retVal = $GLOBALS[$envVar];
//printf "frtf";
if (strlen($retVal) < 1) {
	$retVal = getenv($envVar);
	if (strlen($retVal) < 1) {
		$retVal = $HTTP_ENV_VARS[$envVar];
		if (strlen($retVal) < 1) {
			$retVal = $HTTP_SERVER_VARS[$envVar];
		}
	}
}

return $retVal;

}

I think I found the problem:

function getFormData() {
global $HTTP_GET_VARS;
global $HTTP_POST_VARS;

$requestType = getEnvVar('REQUEST_METHOD');

switch (strtolower($requestType)) {
	case 'get':
		$data = $HTTP_GET_VARS;
		break;
	case 'post':
		$data = $HTTP_POST_VARS;
		break;
	default:
		settype($data, 'array');
}

if (!$data && function_exists('getSpecificFormData'))
	$data = getSpecificFormData();

return $data;

}

This is the code where the function is called. But the REQUEST_METHOD seems to be an Apache variable...is the an alternative for Windows IIS?
