如何在php中检查xml对象是否为空

Question

if ($xml) {
    $emailId            = $xml->mail->id;
    $mailPassword       = $xml->mail->password;
    if (!empty($emailId) && !empty($mailPassword)) {
        $data['emailIdandPasswordCheck']    = 0;
    }
}

this is a condition in which we are checking the values are empty or not but it is not working
in this id is empty and password is not empty.
but everytime xml object is coming in both id and password
because of this both the things are coming as non empty.
what check i can use to check xml object is empty or not?

Answer 1

You can use cast an array and you check the condition

$emailId  = (array)$emailId;
$mailPassword = (array)$mailPassword;
if (!empty($emailId) && !empty($mailPassword) ){

}

OR

$emailId  = (array)$emailId;
$mailPassword = (array)$mailPassword;
if (count($emailId)==0 && count($mailPassword)==0 ){

}
