otuatail Use of undefined constant FETCH_ASSOC

As per the other PDO constants you used in that command, it requires the "PDO" class as part of the identifier: PDO::FETCH_ASSOC (i.e., the constant is specific to the PDO class)

      Does $row['Name_F'] have to be an index as I don't use indexes in this table?

      otuatail TRhis results in crashing the web page with
      This page isn’t working

      That will always be printed because you put it as the first thing the page should do, before you've even attempted to connect to the datatabase.

      I'm also guessing that what you're posting isn't actually what you're running, based on the spurious text in

      $stmt = $pdo->query("SELECT * FROM PDO");
ecPDO");
while ($row = $stmt->fetch())

          Not now. I did change the names in the table.

                So execution is getting that far: rows are being returned, but something is wrong with the contents of those rows. Do some debugging: replace the echo with a simple var_dump($row) to see what exactly it contains.

                (Incidentally, MyISAM isn't appropriate in most situations for safety reasons, and mixing character encodings (UTF8 in one place, latin1 in another) is a good way to corrupt text. And you've misspelled "Freddie" 🙂).

                  otuatail $row = $stmt->fetchAll()

                  The fetchAll() method returns an array consisting of all the rows in the result set, so of course there's no main index named Name_F.

                    Oh yeah, I'm so used to using foreach to iterate over a collection that I completely missed that it said fetchAll and not fetch. It used to say fetch but the OP changed that for whatever reason.
