I want to put my database into html tables but i dont know how to and i have tried a couple but its not working [duplicate]

This question already has an answer here:

• Populating HTML from MySQL & PDO (PHP); foreach loop failing to write MySQL data 3 answers

This is my php file for my page that is displying my database

<?php
  require 'head.php'; 
  require 'testmysql.php';
?>

<?php

   $results = $pdo->query('SELECT * FROM jobs');



   foreach ($results as $row) 
{
      echo '<br>' . $row['id']. ' ' . $row['title']. ' ' .$row['salary'].  ' ' . $row['location']. ' ' . $row['description']. '</br>';
}

?>


<?php 
 require 'foot.php'; 
?>

And this is my seperate file for the connection for my php

<?php
$server = 'localhost';
$username = 'root';
$password = 'admin';
$schema = 'vacancies';
$pdo = new PDO('mysql:dbname=' . $schema . ';host=' . $server, $username, $password);

?>

I am not really familiar with php and i have researched for some html table code for this but it failed everytime. I hope someone could help. Thank you in advance.
