Hi Bruno...
I tried your sample, but it doesn't seem to work. I do however see what you're getting at.
Perhaps I need to experiment with the eregi_replace commands (or other regex commands) a bit.
Thanks,
for what Bruno showed you, you definitly don't need regexps. That example doesn't use regular expressions in case you didn't notice, so would work just as well with a simple str_replace.
Now, the problem with such a "solution" is the following. Imagine you have the following keywords:
include
require
in
of
typof
now, when you replace include with <span class="highlighted">include</span>, it'll go on, and also replace all instances of in, so you'll end up with things like <span class="highlighted"><span class="highlighted">in</span>clude</span> (very ugly).
*a* way to get around that is by using word boundries around the keyword to be replaced (eg. preg_replace('\(\W|^)+('.$highlight[$i].')(\W|$)\i', '$1<span class="highlight">$2</span>$3') )
