Question

$mysql_connection = new mysqli(blah blah blah..
$query = "SELECT * FROM posts ORDER BY id DESC";
$result = $mysql_connection->query($query);

That little last instruction here generates a 500 Internal Server Error in my site, I didn’t posted the whole code because I didn’t want to make you stay hours to read it.
I tested it by printing something after every instruction that may have caused the error, and when it reaches the query part, id stops.

I’m a very beginner in PHP, so sorry if it’s a dumb question.

So, any little hint will be very appreciated.

Answer 1

it looks like the connection is not going through for some reason
can you add this to your code and post the output

if ($mysqli->connect_error) {
    die('Connect Error (' . $mysqli->connect_errno . ') '
            . $mysqli->connect_error);
}
