Printing out MySQL table names with PHP

So I want to get each table name in a MYSQL database and put it in the variable database.  This is what I have so far but I cant seam to get it working, thanks in advance!  It just says "Access denied for user ''@'localhost' to database 'mynotesdatabase'" But when I print out the actual rows of the tables it works but not when I want to print out the table names.

if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }
  else{
  echo "Connected", "<br/>";
  }
  
  
  
  
   $query = mysql_query("SHOW TABLES FROM mynotesdatabase") or die(mysql_error());



 while($row = mysql_fetch_array($query)) {

$database = $query;
 
$result = mysqli_query($con,"SELECT * FROM $database");
echo "<b>+" . $database . "</b><br/>";
while($row = mysqli_fetch_array($result))
  {
  $type = "";
  if($row['Type'] == 0){
  $type = "Link";
  }
  else{
  $type="Note";
  }
  echo "&nbsp -" . $row['Name'] . " (" . $type . ")";
  echo "<br>";
  }
  
  
 }
 
 


mysqli_close($con);
