How can we highlight a full word and a partial word in php?

Below is my code, I want to highlight a full word and a partial word. The code below just highlights the full word but not the partial word.

For example :

$text = "this is a very famouse poem written by liegh hunt the post want to impress upon the importance";

AND

$words ="very written hu want impor";

I want output like below :-

"this is a very famouse poem written by liegh hunt the post want to impress upon the importance";

Function that i have created for it:-

function highlight($text, $words) {
    preg_match_all('~\w+~', $words, $m);
    if(!$m)
        return $text;
    $re = '~\\b(' . implode('|', $m[0]) . ')\\b~i';
    return preg_replace($re, '<b style="color:white;background-color:red;border-radius:2px;">$0</b>', $text);
}

Stop struggling with regular expressions when you have inbuilt functions in php.

Same functionality with pure php. without using regular expression, by ignoring case sensitive.

<?php

 $words = "very written hu want impor";
 $words = explode(' ', $words);

function hilight($text, $words){
   foreach ($words as $value) {
    $text = str_ireplace($value,'<b style="color:white;background-color:red;border-radius:2px;">'.$value.'</b>',$text);
   }
  return $text;
}

$text = "this is a very famouse poem written by liegh hunt the post want to impress upon the importance";
echo hilight($text, $words);

?>
