Everybody! This is important. In a few days, these forums will be moving over to using the totally sweet Discourse platform. To ensure this migration happens smoothly with no loss of content, these forums are currently in a read-only mode. I do apologize for the inconvenience.

There is never a good time to turn the forums off for an extended period of time, but I promise the new forums will be a billion times better. I'm pretty sure of it.

See you all on the other side in a few days, and if you have any (non-technical) questions, please e-mail me at kirupa@kirupa.com. For technical questions, try to find a tutorial that corresponds to what you are looking for and post in the comments section of that page.

Cheers,

Thread: pre_replace not sure what the correct expression is

    pre_replace not sure what the correct expression is

    Hi all

    I need to scan a block of body copy that will replace certain words within the copy with other words.

    I can do this is and got this part working.

    How ever i need it to replace only words out side of any html tags. <.*> </.*> < />

    So if the word appears in a link its ignored.

    Any ideas on how to do this?

    my code so far

    PHP Code:

    $patterns
    [] = '/'.$tag.'(?![^<]*>)/i';
    $replacements[] = '<a  href="'/'.$tag.'"  >'.$tag.'</a>'; 
    Thanks

    An intellectual carrot!
    You could try something like this:

    preg_replace("~(>.*?)(word)(.*?<)~s", '${1}new_word$3', $data);

    Of course, your tags would all need to be balanced and your html characters (namely '>' and '<') would need to be encoded (ie, '&gt;' and '&lt;'). At the very least, that should get you closer... good luck!
