Uncaught Error: Call to undefined method DB::execute() - php

I am using indieteq-php-my-sql-pdo-database-class I found on GitHub
I have created a little page to try and display some database information as seen below, however I receive the error below my test page script below;
My Test Page
<?php
require("Db.class.php");
$db = new Db();
$db->query("SELECT * FROM faction_territories");
if ($db->execute()) {
while ($row = $db->fetch(PDO::FETCH_ASSOC)) {
echo '<tr>
<td>'.$row['territory_id'].'</td>
<td>'.$row['name'].'</td>
<td>'.$row['density'].'</td>
<td>'.$row['sector'].'</td>
<td>'.$row['size'].'</td>
<td>'.$row['respect'].'</td>
<td>'.$row['faction_name'].'</td>
</tr>';
}
echo '</table>';
}
?>
Error
Fatal error: Uncaught Error: Call to undefined method DB::execute() in
/var/www/.../index.php:7 Stack trace: #0 {main} thrown in
/var/www/.../index.php on line 7
Questions
As you'll be able to tell, I'm somewhat new to PHP & PDO. Some nice pointers to where I am going wrong would be nice with any example code please.

The $db->query already execute the query. You just need to iterate over the result.

Is it possible to use DOM on an external webpage?

I like to use the list on this page: list of teams of soccerclub
But I always get this error
Fatal error: Uncaught Error: Call to a member function find() on null in /home/u562375926/domains/lucswebsite.tech/public_html/resp/scrapvv.php:152 Stack trace: #0 {main} thrown in /home/u562375926/domains/lucswebsite.tech/public_html/resp/scrapvv.php on line 152
using this code:
<?php
include('simple_html_dom.php');
$file = 'https://www.voetbalvlaanderen.be/club/1771/ploegen';
$html = new simple_html_dom();
$html->load_file($file);
$club = $html->find('div',8)->find(h2);
echo $club. '<br>';
?>
I have used the same page in ParseHub and I get all a hrefs and the text of the corresponding spans.
Is it possible that DOM is not working on that page?

getQty() giving fatal error in magento 1.9

I am trying to get the collection based on product and quote Id using,
$quotecollection = Mage::getModel('sales/quote_item')->getCollection()->addFieldToFilter('quote_id',$quoteId)->addFieldToFilter('product_id',$product_id);
$quotecollectionaArr = $quotecollection->getData();
echo $quotecollection->getQty();
which gives the following error
Fatal error: Call to undefined method
Mage_Sales_Model_Resource_Quote_Item_Collection::getQty() in
C:\xampp\htdocs....
Please help.
You should use getFirstItem()
$quotecollection = Mage::getModel('sales/quote_item')->getCollection()->addFieldToFilter('quote_id',$quoteId)->addFieldToFilter('product_id',$product_id)->getFirstItem();
echo $quotecollection->getQty();

Fatal error: Call to undefined method with Wordnik API

Not sure if this is an Wordnik API issue or just a php error on my part. Here is my current code:
require('./wordnik/Swagger.php');
require('./wordnik/WordsApi.php');
$myAPIKey = '00144cdc1140c4192780f08c3f608399234240dcb560d3e4b';
$client = new APIClient($myAPIKey, 'http://api.wordnik.com/v4');
$wordApi = new WordApi($client);
$input = new WordObject();
$input->includePartOfSpeech='noun';
$input->excludePartOfSpeech='affix,article,connjunction,preposition,abbreviation,suffix';
$input->hasDictionaryDef='true';
$input->minCorpusCount='10000';
$input->maxCorpusCount='null';
$input->minDictionaryCount='20';
$input->maxDictionaryCount=null;
$input->minLength='4';
$input->maxLength='20';
$random_word = $wordApi->getRandomWord($input); //THIS IS THE ERROR LINE
print $random_word->text;
and here is the error I get:
Fatal error: Call to undefined method WordApi::getRandomWord()
Any help is greatly appreciated. The error is happening on that line towards the bottom, just not sure why. Thank you.
getRandomWord() is defined in WordsApi (plural words).
You have: WordApi
You need: WordsApi

How can I fix this PHP XML parsing error?

This is my first question :).
Im writing a little twitter app in PHP that sends a DMs to all your followers. What im trying to do right now is to get the list of followers. So through twitter api and getting all usernames but for some reason this parsing error appear. Im new to php(but not so much to programming), I actually started learning it yesterday so please be easy on me ;).
Here is the code:
$t= new twitter();
$t->username= $_GET["username"];
$t->password= $_GET["password"];
$fi = $t->followers();
$xml[$page] = new SimpleXMLElement($fi[2]);
$user1count=0;
while(isset($xml[$page]->user[0])){
foreach ($xml[$page]->user as $user) {
$userdet[(string)$user->screen_name]=array( ’screen_name’=> (string)$user->screen_name, ‘location’=>(string)$user->location, ‘description’=>(string)$user-> description, ‘profile_image_url’=> (string)$user-> profile_image_url, ‘url’=>(string)$user-> url, ‘name’=>(string)$user->name );
$user1details[$user1count]= (string)$user->screen_name;
$user1count++;
}
$page++;
$fi=getfilecontents($friendsurl.$username1."xml?page".$page);
if($fi[0]===false){
echo ("Error :".$fi[1]);
$err=new SimpleXMLElement($fi[2]);
echo " ".$err->error." ";
// echo ““;
die();
}
$xml[$page] = new SimpleXMLElement($fi[2]);
}
And the error said:
Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in /Applications/XAMPP/xamppfiles/htdocs/scripts/dmsend.php:125 Stack trace: #0 /Applications/XAMPP/xamppfiles/htdocs/scripts/dmsend.php(125): SimpleXMLElement->__construct('') #1 {main} thrown in /Applications/XAMPP/xamppfiles/htdocs/scripts/dmsend.php on line 125
Thank you! :)
It looks like $fi[2] is not a valid xml string. I am not 100% familiar with the twitter API, but I would do a var_dump($fi) and evaluate what is begin returned. From there, you should be able to figure out what is happening.
