I am trying to learn php and mysql. So i tried making a database using phpmyadmin and connect it with my php.
Here is a simple example where I try to see if the database is working

<?php
$connection = mysql_connect("localhost","root");
if(!$connection) {
    die("Database connection failed: " . mysql_error());
    $db_select = mysql_select_db("nameofdatabase",$connection);
    if (!$db_select) {
        die("Database selection failed:: " . mysql_error());
        }
    }
?>
<html>
<head>
<title>Databases</title>
</head>
<body>
<?php
$result = mysql_query("SELECT * FROM nameofdatabasetable", $connection);
if (!$result) {
    die("Database query failed::: " . mysql_error());
}
while ($row = mysql_fetch_array($result)) {
echo $row[1];
}

?>

</body>
  </html>
<?php
mysql_close($connection);
?>

and i get 

 Database query failed::: No database selected

which means than this part of code

<?php
$result = mysql_query("SELECT * FROM users", $connection);
if (!$result) {
    die("Database query failed::: " . mysql_error());
}
while ($row = mysql_fetch_array($result)) {
echo $row[1];
}

?>

is not working (i put a different number of these “:” in each if.
Any help would be appreciated! Thank you!

    The logic for your code doesn’t make sense because if the connection doesn’t happen then you would not be able to select a database and your database select statement is within the logic for if you cannot connect to the database. Try this instead:

    $connection = mysql_connect("localhost","root"); 
if(!$connection) { 
   die("Database connection failed: " . mysql_error()); 
}else{
   $db_select = mysql_select_db("nameofdatabase",$connection); 
   if (!$db_select) { 
       die("Database selection failed:: " . mysql_error()); 
   } 
}
