* $text - The text to operate on.

* $open_tag - The opening tag to match. Can be an array of opening tags.
* $close_tag - The closing tag to match.
* $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.
