php check getvalue is not null

Question

I get this output as an array $vcard:

object(Sabre\VObject\Component\VCard)#11987 (6) {
  ["children":protected]=>
  array(1) {
    ["EMAIL"]=>
    array(1) {
      [0]=>"mail@domain.de"
    }
   }
}

With this code I get the value of EMAIL:

echo $vcard->EMAIL->getvalue()

The problem: If the key "EMAIL" doesn't exist I get this error:

Notice: Undefined index: EMAIL
Fatal error: Uncaught Error: Call to a member function getvalue() on null

How can I handle this error?

It'd be `$vcard->children['EMAIL']` if I'm not wrong, but `children` is protected. Where does `getvalue()` come from exactly? A `var_dump()` display won't show methods. — Álvaro González, Jan 14 '21 at 07:44
I'm using this lib: https://github.com/mstilkerich/carddavclient — Trombone0904, Jan 14 '21 at 08:38
Fix the first error first, that will in turn help you solve the second error. — Qirel, Jan 14 '21 at 11:31

It works !

if($email = $vcard->EMAIL) {
   echo $vcard->EMAIL->getValue();
} else {
   echo "NOT OK";
}
