I implemented following script in PHP for GetVerifiedStatus method with API call and it is working fine for me. This script is for sandbox so if you want to test it, please test it with sandbox PayPal accounts. If you want to use it for production mode, then delete the lines for sandbox (I showed them in the comment hints) . I explained about the things you need to get from paypal to run this code inside the PHP comments.
<?php
// create a new cURL resource
$ch = curl_init();
$ppUserID = "******************"; //Take it from sandbox dashboard for test mode or take it from paypal.com account in production mode, help: https://developer.paypal.com/docs/classic/api/apiCredentials/
$ppPass = "*************"; //Take it from sandbox dashboard for test mode or take it from paypal.com account in production mode, help: https://developer.paypal.com/docs/classic/api/apiCredentials/
$ppSign = "********************"; //Take it from sandbox dashboard for test mode or take it from paypal.com account in production mode, help: https://developer.paypal.com/docs/classic/api/apiCredentials/
$ppAppID = "***********"; //if it is sandbox then app id is always: APP-80W284485P519543T
$sandboxEmail = "********************"; //comment this line if you want to use it in production mode.It is just for sandbox mode
$emailAddress = "******************"; //The email address you wana verify
$firstName = "********"; //first name of the account holder you want to verify, sandbox personal account default first name is: test
$lastName = "*******"; //last name of the account holder you want to verify, sandbox personal account default last name is: buyer
//parameters of requests
$nvpStr = 'emailAddress='.$emailAddress.'&firstName='.$firstName.'&lastName='.$lastName.'&matchCriteria=NAME';
// RequestEnvelope fields
$detailLevel = urlencode("ReturnAll"); // See DetailLevelCode in the WSDL for valid enumerations
$errorLanguage = urlencode("en_US"); // This should be the standard RFC 3066 language identification tag, e.g., en_US
$nvpreq = "requestEnvelope.errorLanguage=$errorLanguage&requestEnvelope.detailLevel=$detailLevel";
$nvpreq .= "&$nvpStr";
curl_setopt($ch, CURLOPT_POSTFIELDS, $nvpreq);

curl_close($ch);
$data = json_decode($paypalResponse);
if($data->responseEnvelope->ack == "Success"){
$output = array('status' => true); //means user is verified successfully
} else {
$output = array('status' => false); //means verification was unsuccessful
}
echo $output;
?>
