Regex For replacing [intro]

[Eric.Coleman]

Im tring to use this:

function prep_data($string) {

        $intro_string = preg_replace ('/(.*)?\\[intro\\]/i', '', $string);
        $intro_string = preg_replace ('/\\[\/intro\\](.*)/i', "", $intro_string);
        // now finish off $string
        $string = preg_replace('/\\[intro](.*)?\\[\/intro\\]/i', "", $string);
        // run through text->links function
        //$intro_string = $this->textlinks($intro_string);
        //$string = $this->textlinks($string);
        $fd = array("intro" => $intro_string, "body" => $string);

        return $fd;
    } 

What it's supposed to do, is take something like

[intro]
This is intro!
[/intro]
This is the body

And seperate it into 2 strings, one being "This is intro!" and the other being "This is the body"

Now, it only works if it is like this:

[intro]This is intro![/intro]This is the body

So what am I doing wrong? (this is my first self written regex, if it's even called that)

. doesn't match a newline character. Try the /s modifier; in Perl this is supposed to make the regexp treat the multi-line text as one line. For example you'll have /(.*)?\[intro\]/is for a pattern.

That worked, but now it's leaving a \n after each split, i.e. the intro text starts with \n and the body text starts with \n

Why not just do a str_replace. It is cheaper than *reg_replace. Of course, that would mean that [intro] without a closing intro could mess up page formatting, perhaps you could add to a stack every time a [intro] is replaced and then pop it when you reach a closing intro [/intro].

I got it working, but now I still have this \n after I split it, which doesn't really need to be there.. or does it?

I swear, sometimes the biggest moron is actually yourself..

I totaly forgot about trim() which solved the last of my problems,

Thanks for all the help
