You can split the found string into an array ( explode ) and then search this array with the given string ( preg_grep ) and output the found strings.

<?php
$searchString = "/res/";
$foundString = "some text restaurant and other";
$explode = explode(" ", $foundString);
$searched = preg_grep($searchString, $explode);

foreach($searched as $item) {
  echo $item . " ";
}
