How to parse Telegram message by comma, but keep commas that are in parenthesis-CodePudding

I have a PHP script that parses a telegram history message. It is comma separated, but grouped by parenthesis. I have tried a lot of things. Here is my current code that does not parse correctly.

$message = "Message(id=1650, peer_id=PeerChannel(channel_id=1286966173), date=datetime.datetime(2022, 4, 15, 17, 14, 25, tzinfo=datetime.timezone.utc), message='Please check your email inbox', out=False, mentioned=False, media_unread=False, silent=False, post=True, from_scheduled=False, legacy=False, edit_hide=False, pinned=False, from_id=None, fwd_from=None, via_bot_id=None, reply_to=None, media=None, reply_markup=None, entities=[], views=382, forwards=0, replies=None, edit_date=None, post_author=None, grouped_id=None, restriction_reason=[], ttl_period=None)04-18-2022 01:25am";
$keywords = preg_split("/,(?![^(] \))/", $message);
foreach($keywords as $value){
    echo "$value<hr>";
}

I am looking to parse the date and message.

You can chain a couple of regexes together and do some data transformation to get the result as a PHP array.

This output looks like it has been printed with Python, instead of using a script to parse the python dump, I'd recommend modifying the python script to output something easier to parse.

$raw_message = "Message(id=1650, peer_id=PeerChannel(channel_id=1286966173), date=datetime.datetime(2022, 4, 15, 17, 14, 25, tzinfo=datetime.timezone.utc), message='Please check your email inbox', out=False, mentioned=False, media_unread=False, silent=False, post=True, from_scheduled=False, legacy=False, edit_hide=False, pinned=False, from_id=None, fwd_from=None, via_bot_id=None, reply_to=None, media=None, reply_markup=None, entities=[], views=382, forwards=0, replies=None, edit_date=None, post_author=None, grouped_id=None, restriction_reason=[], ttl_period=None)04-18-2022 01:25am";

$strip_message = '';
preg_match("/Message\((.*)\)/", $raw_message, $strip_message);

$split_by_comma = array_map('trim', preg_split("/,(?![^()]*\))/", $strip_message[1]));

$message=[];

foreach ($split_by_comma as $element) {
    $split_by_equals = explode('=', $element);
    $key = array_shift($split_by_equals);
    $value = implode('=', $split_by_equals);
    if ($key !== 'message' && $key !== 'date') {
        $message[$key] = $value;
        continue;
    }

    if ($key === 'date') {
        $date_tmp = '';
        preg_match("/\((.*)\)/", $value, $date_tmp);
        $date_split = explode(', ', $date_tmp[1]);
        $date = $date_split[0] . '-' . $date_split[1] . '-' . $date_split[2] . ' ' . $date_split[3] . ':' . $date_split[4] . ':' . $date_split[5];
        $message[$key] = $date;
    }

    if ($key === 'message') {
        $message[$key] = str_replace("'", '', $value);
    }
}

var_dump($message);

Results in:
