Urgent Help matching contents

Hey, I need a bit of help replacing some variables in a string. I know its done with preg_replace.

 

Here is the string:

 

Header 1 <|header 2|> header 3 <b>header 4</b>

I would like to get ONLY <|header 2|> from the above string. But "header 2" is variable so please its useless if the preg_replace isn't flexible to find whatever word is in there regardless.

 

Thanks you.

$string = preg_replace('#<|.*?|>#', $replacement, $string);

 

Something like that should suffice.
