Trying to fix QUOTES from Invision import

[pattycake]

i was just trying to do a quick test by assigning the data that was in the database to a var, and then running the preg_replace on that var so I can see before and after. I do a $test= on that data in the box up above and then do the preg_replace on $test


what exactly does this preg_replace do?

$text = preg_replace('#<!--QuoteBegin-->([^"]*)<!--QuoteEBegin-->#siU', '[quote][b]', $text);

I understand the # delimiters, but not that stuff inside the [], or the siU at the end, or the two QuoteBegin and QuoteEBegin.... why are there two of them?

I do know that if I try to run this on my var, it doesn't change anything.

same for this one:

$text = preg_replace('#<!--QuoteBegin-{1,2}([^"]*)\+-->([^"]*)<!--QuoteEBegin-->#si', "[quote]Originally posted by \\1\n[b]", $text);

what does that {1,2} thingie?
