Since, as far as I can tell, the preg_replace() replacement parameter can't deal with using $1 as a key in an existing hash, here's an ugly hack that does just that: $string = "asdf[[foo]]asdf[[bar]]asdf"; $args = array("foo"=>"BAR", "bar"=>"PACO"); while(preg_match("/^(.*)\[\[(\w+)\]\](.*)$/", $string, $match)) { $string = $match[1] . $args[$match[2]] . $match[3]; } It would be nice if $string = preg_replace("/\[\[(\w+)\]\]/", $args["$1"], $string); worked but it don't. -- http://www.php.net/manual/en/function.preg-replace.php http://master.php.net/manage/user-notes.php?action=edit+20214 http://master.php.net/manage/user-notes.php?action=delete+20214 http://master.php.net/manage/user-notes.php?action=reject+20214
