I am trying to change the color to red on certain words on my site. However the below code changes each word to "array".

Can someone tell me what is wrong with my code?

function replace_content($content)
    {
    $newwords = array("Check", "Map", "Comments", "Send", "Print");
    $content = str_replace($newwords, '<span style="color:red">' . $newwords . '</span>', $content);
    return $content;
  }
  add_filter('the_content','replace_content');

• That happens, because you've put an array into the string: '<span style="color:red">' . $newwords . '</span>'. – fuxia ♦ Commented Sep 19, 2015 at 20:02
• Thanks, this led me to further research and I was able to get it to work with this: – Brendan Commented Sep 19, 2015 at 20:37
