Answer 1

<?php
$banned = array('word1','word2','word3','word4');

$hit = false;
foreach ($banned as $banned_item)
{
    if (strpos($title, $banned_item) !== false)
    {
        $hit = true;
        break;
    }
}

if ($hit)
{
    // $title contains a banned word
}
else
{
    //$title not contains any word of $banned variable array
}

The code above is case-sensitive, if you want your code be case-insensitive, just change:

  if (strpos($title, $banned_item) !== false)

to:

  if (stristr($title, $banned_item) !== false)
