Please create a simple function in procedural PHP coding. The function will have to get the words given into an array(feel free to chose the kind), and for each one check if a stop word is found. In case the stop word is found the function will have to replace the characters with asterisks. The stop words are located into the DB in a table named…

sample.php

<?php

/**
 * Filter stop words in the given array of words.
 * 
 * @param array $words Array of words to filter.
 * @return array
 *   New array with filtered words (replaced with asterisks).
 */
function filter_stop_words($words) {
  $db = new PDO('mysql:host=localhost;dbname=sites_sandbox;charset=utf8', 'root', '123Qwe');
  $query = $db->query('SELECT stop_word FROM stop_words INNER JOIN common_words ON common_words.ID_stop_word != ID');
  $stop_words = $query->fetchAll(PDO::FETCH_COLUMN, 0);

  $replacements = array_map(function($item) {
    return str_repeat('*', strlen($item));
  }, $stop_words);

  return str_replace($stop_words, $replacements, $words);
}
