preg_replace within the preg_replace

Question

Right now I\'m having issues replacing strings that already come out from preg_match. Lets say I have bbcode of [b]bla[/b], I have this part working with replacing

You could do something like this:

$string = '[b]hi [b]test[/b][/b]';    
do {
    $string = preg_replace('/\[b\](.*)\[\/b\]/', '$1', $string, -1, $count);
} while ($count > 0);

Or just use @Justinas' idea (from your OT's comment) if it's OK to replace all [b] with and [/b] with (regardless of them being in the right order/as pairs).

Edit: you also need to change your quote regex to this:

/\[quote(?:=(\d+))?\](.*)\[\/quote\]/s

s flag allows . to match newlines (you probably want to add it to the other ones too). I also fixed the quote ID capturing part.
