Re: Syntax highlighting of odd language

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).

I did encounter this during some experimenting. I figured I'd just sort the array of commands from from shortest strong to longest string. But like you said, far too many embedded <span> tags would result!

*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') )

My regular expression skills are very basic, but I understand the gist of your preg_replace statement. Now I just need to polish my regex knowledge! Thanks, -- Aaron Gould Parts Canada - Web Developer
