PHP - Header() Not Working : So Simple A Case But Help Needed

hello dear php-experts,

i fairly new to simple_html_dom usage and methods. I know a little the parser,
 
i want to gather some information from this site:

https://europa.eu/youth/volunteering/organisations_en#open

is this possible to get the content - of let us say 10 or 20 last records on that page - and subesquently to store it in my mysql - db!?

<?php
// Report all PHP errors (see changelog)
error_reporting(E_ALL);

include('inc/simple_html_dom.php');

    //base url
    $base = 'https://europa.eu/youth/volunteering/organisations_en#open';

    //home page HTML
    $html_base = file_get_html( $base );

    //get all category links
    foreach($html_base->find('a') as $element) {
        echo "<pre>";
        print_r( $element->href );
        echo "</pre>";
    }

    $html_base->clear(); 
    unset($html_base);

?>

I have the above code and I'm trying to get certain elements of the page but it isn't returning anything. 

Is it possible that certain PHP functions might be disabled on the server to stop that?

The above code works perfectly on other sites.

Is there any workaround?

btw:  i have created a small snipped as a proof of concept to run this with Python and BeautifulSoup - 

import requests
from bs4 import BeautifulSoup
 
url = 'https://europa.eu/youth/volunteering/organisations_en#open'
response = requests.get(url)
soup = BeautifulSoup(response.content, 'lxml')
print(soup.find('title').text)
block = soup.find('div', class_="eyp-card block-is-flex")

and this.... 

European Youth Portal
>>> block.a
<a href="/youth/volunteering/organisation/48592_en" target="_blank">"Academy for Peace and Development" Union</a>
>>> block.a.text
'"Academy for Peace and Development" Union'
 
>>> block.select_one('div > div > p:nth-child(9)')
<p><strong>PIC:</strong> 948417016</p>
>>> block.select_one('div > div > p:nth-child(9)').text
'PIC: 948417016'

what is aimed in the end - i want to gather the first 20 results of the page - and put them in to a sql-db or alternatively show the information in a little widget 

http://localhost/vehicles/show.php?plate_number=f%20f%20f%205%205%205%205

search about plate_numbet = f f f 5 5 5 5

// pdo connection.

// first sql test 
$sql = "SELECT * FROM vehicles WHERE plate_number LIKE '%".$_GET['plate_number']."%'"; 

// second sql test
// $sql = "SELECT * FROM vehicles WHERE plate_number = '".$_GET['plate_number']."'";

$db->query($sql); 
if($db->rowcount() > 0){ 
// print all results... 
}else{
echo "There are no results.";
}

SELECT * FROM vehicles WHERE plate_number LIKE '%f f f 5 5 5 5%';

OR 

SELECT * FROM vehicles WHERE plate_number = 'f f f 5 5 5 5';
