Php Arrays/Table's need to get "EntityId" - php

Question

I am new to tables/arrays and I can't get this to work.
I am trying to get The data of "EntityId", and it doesn't work if I change "Phone" to "EntityId". I tried much more but I can't figure it out on my own. I hope someone can explain what I am doing wrong or maybe I did't notice something.
Any help would be appreciated.
Script
<?php
require_once 'autoload.php';
$username = '*****************';
$password = '*********';
$authWsdl = 'https://webservices.autotask.net/atservices/1.5/atws.wsdl';
$opts = array('trace' => 1);
$client = new ATWS\Client($authWsdl, $opts);
$zoneInfo = $client->getZoneInfo($username);
$authOpts = array(
'login' => $username,
'password' => $password,
'trace' => 1, // Allows us to debug by getting the XML requests sent
);
$wsdl = str_replace('.asmx', '.wsdl', $zoneInfo->getZoneInfoResult->URL);
$client = new ATWS\Client($wsdl, $authOpts);
// Instantiate a Query object, designed to make complex
// queries simple.
$query = new ATWS\AutotaskObjects\Query('Contact');
$firstnameField = new ATWS\AutotaskObjects\QueryField('ID');
$firstnameField->addExpression('Equals', '30682996');
$query->addField($firstnameField);
// If you want to debug the XML produced by the Query object
// print($query->asXml());
// Print the results of the query
print_r($client->query($query));
$json = ($client->query($query));
$phone = $json->queryResult->EntityResults->Entity->Phone;
echo $phone;

If i understand your problem you are looking for this:-
echo $json->queryResult->EntityResults->Entity->UserDefinedFields->UserDefinedField->EntityReturnInfoResults->DatabaseAction->EntityReturnInfo->EntityId;
