OT: Highlighting keywords in content - PHP

Yes, its one of those things that sounds complex, but is actually really
easy :-)

Just do a standard batch replace, it doesn't matter if the keywords not
found as nothing will be done, although the keyword should be in there if
its a search result. You just need a couple of replaces to make sure you hit
all combinations of the word eg KEYWORD,keyword,Keyword. The str_replace()
command is faster than using regular expressions, so its the prefered
method.

Gareth, this is really easier than I had thought. You are doing a batch
replacement instead of looking for a match first. Brilliant.

Thanks!

Yes, your spot on. I`d always thought it would be complicated, but decided
to give it a go the other day, and realised that it was actually incredibly
simple when I thought about it, one of those DOH! moments :-)

In PHP its as simple as:

$text = str_replace($keyword,"<span class='highlight'>" . $keyword .
"</span>",$text);

Its best to create a custom function to do the above looping through the
list of keywords, and using ucase() etc to get words where the whole word is
in uppercase, lower case, or the first letter is uppercase.

Looks really effective!
