Highlight particular words

Geronantimo · Apr 7, 2006

I have some web pages with dynamically generated content and I wonder if PHP can be used to highlight particular words that I choose.

There seem to be plenty of methods for highlighting search terms or for the user to choose words to highlight, but I would like to specify which words are highlighted (if they appear in the content).

I'd be grateful for being pointed in the right direction. Is it even possible?

Yes it's possible, look around for php highlighting, and I've seen a few, I don't have any references off hand but they do something similar to google toolbar's highlight.

you could try something like this

Code:

$words = array("apple","apples", "banana", "bananas", "cabbage", "cabbages");
$colour = "blue";
$str = "apples are green, bananas are yellow and cabbage is disgusting";

foreach ($words as $srch):
  $str = str_replace($srch, "<span style=\"color:$colour;\">$srch</span>", $str);
endforeach;
echo $str;
