Maybe something like this?
<?php
$words = array("php", "language");
$str = 'One language which is great is php. PHP works great!';
$str = strtolower($str);
echo '<pre>';
foreach($words as $word) {
echo 'word = ' .$word;
echo ' (' . substr_count($str, $word). ")\n";
}
echo '</pre>';
?>
Although you'll run into a problem if your words array contains for
example 'air' which will match both 'air' and 'fair',
