Highlight partly matched keywords

I picked up this code from stackoverflow to bold matched keywords. But it only bold exactly matched keywords.

For example:

$text = "iphone" and $srch_term = "iphone" -> matched and bold it

$text = "iphone" and $srch_term = "iph" -> No matched (I would like it to be matched and bold as well)

How can i fix this code below to achieve this goal? Sorry I have limited knowledge of using regex so I am not sure what to do with it.

function highlightWords($text, $srch_term) {
preg_match_all('~\w+~', $srch_term, $m);
if(!$m)
    return $text;
$re = '~\\b(' . implode('|', $m[0]) . ')\\b~i';
return preg_replace($re, '<b>$0</b>', $text);
}

$re = '~(' . implode('|', $m[0]) . ')~i';

Use this.Remove \b as it will look for word boundaries.

\b assert position at a word boundary (^\w|\w$|\W\w|\w\W)
