Nested quotes preg_replace regex

I currently have the following regex:

\[quote="([^"]+)"\]([^[]+)\[\/quote\]

Which matches [quote="author"]text[/quote] in a string and captures author and text to convert it to a formatted div quote:

$p_text = preg_replace('/\[quote="([^"]+)"\]([^[]+)\[\/quote\]/', '<div class="quote"><strong class="quote-author">$1 wrote:</strong><br>$2</div>', $p_text);

However I want to be able to nest it once, like this:

[quote="b"]

    [quote="a"]
        Original text
    [/quote]

Reply to quote a
[/quote]

Reply to quote b

Here's how I want it to look:

Here's how it currently looks with the code above:

How can I nest the quotes?

You can resolve it from inside out with your current regex by using a loop.

$pattern = '/\[quote="([^"]+)"\]([^[]+)\[\/quote\]/';
$replace = '<div class="quote"><strong class="quote-author">' .
           '$1 wrote:</strong><br>$2</div>';
do {
  $p_text = preg_replace($pattern, $replace, $p_text, -1, $replace_count);
} while($replace_count > 0);

See demo at eval.in. If you need a recursive regex for whatever reason, see this demo at regex101.
