Question

Please take a look at this code (thanks to user budwiser), it matches a certain word in a text and ads a span class to it:

function highlightWord($word, $text){
    return str_replace($word, '<span class="highlighted">' . $word . '</span>', $text);
}

$text = highlightWord('fitness', $text);

Any ideas how to make this code work for arrays?

I’d need something like this:

$words = array("fitness", "aerobic", "fashion");

$text = highlightWord($words, $text);

Any ideas?

Thank you!

UPDATE

$profile_rule = 'profile LIKE (\'fitness\') AND profile LIKE (\'aerobic\')';
preg_match_all('/\'(.*?)\'/',$profile_rule,$match);

Any idea why $match array does not work?
I want to extract the words fitness and aerobic from the $profile_rule and use the $match array for the function above.

Ty!

This should do the trick. Simply iterate over the words and add the highlight code.

function highlightWords(Array $words, $text)
{
   // Loop through array of words
   foreach($words as $word)
   {
      // Highlight word inside original text
      $text = str_replace($word, '<span class="highlighted">' . $word . '</span>', $text);
   }

   // Return modified text
   return $text;
}
