 * $text - The text to operate on.

 * $close_tag_new - The closing tag to replace with.
 * $mark_lowest_level - boolean - should we specially mark the tags that occur
 *                     at the lowest level of nesting? (useful for [code], because
 *                        we need to match these tags first and transform HTML tags
 *                        in their contents..
 * $func - This variable should contain a string that is the name of a function.
 *                That function will be called when a match is found, and passed 2
 *                parameters: ($text, $uid). The function should return a string.
 *                This is used when some transformation needs to be applied to the
 *                text INSIDE a pair of matching tags. If this variable is FALSE or the
 *                empty string, it will not be executed.
 * If open_tag is an array, then the pda will try to match pairs consisting of
 * any element of open_tag followed by close_tag. This allows us to match things
 * like [list=A]...[/list] and [list=1]...[/list] in one pass of the PDA.
 *
 * NOTES:    - this function assumes the first character of $text is a space.
 *                - every opening tag and closing tag must be of the [...] format.
