when running code with correct uid, pwd getting false every time. so I debug the code then got "invalid login" every time. with wrong and correct uid, pwd

invalid login
D:\wamp\www\Way2SMS-API-master\sendsms.php:72:
array (size=1)
0 =>
array (size=3)
'phone' => string '8829980508' (length=10)
'msg' => string 'YOUR MESSAGE ' (length=13)
'result' => boolean false

"invalid login" is getting every time from way2sms-api.php page. on these lines :
$pos = stripos(curl_getinfo($this->curl, CURLINFO_EFFECTIVE_URL), "ebrdg.action");
if ($pos === "FALSE" || $pos == 0 || $pos == ""){
echo "invalid login";die();
//return "invalid login";
}
