Excluding text within HTML tags in a replacement

[Dan Grossman]

I'm trying to allow a person to highlight a word or phrase every time it occurs in the page they are viewing. $highlight is captured through a form on the page and specifies that word/phrase to be highlighted. All the code for the rest is fine, except I don't know enough about regex to exclude words within HTML tags from being replaced by this, messing up the pages. $content contains the HTML of the page that gets echoed after a bunch of replaces like this one to fill in variables in my templates.

eregi_replace("$highlight","<span style=\"background: yellow\"><b>$highlight</b></span>",$content);

If they type in the word "hidden", it'll obviously mess up any hidden input tags, for example. Does anyone know how to do this? Thanks in advance.

switch to preg_replace() and then see this thread: http://www.sitepointforums.com/showt...threadid=99025
