Answer 1

Once you have successfully established a connection to MySQL, you need to perform a query specifying what you want to retrieve and then subsequently retrieve it.

The following example uses mysqli_fetch_row

You should explore the documentation to learn the basics.

$db = mysqli_connect('localhost', 'my_user', 'my_password', 'my_db');

if(mysqli_connect_errno()){
    echo'Database connection failed with the following error: '.mysqli_connect_errno();
    exit;
}

if ($result = mysqli_query($db, "SELECT MyCol1,MyCol2 FROM MyTable")) {
    while ($row = mysqli_fetch_row($result)) {
        echo"{$row[0]} - {$row[1]}<br>");
    }
    mysqli_free_result($result);
}

mysqli_close($db);

Answer 2

$db = mysqli_connect('localhost', 'my_user', 'my_password', 'my_db');
$sql="SELECT * FROM login";

here i connected and stored my database and set a sql command (which is now a string) into these two veriables.

if(mysqli_connect_errno()){
    echo'Database connection failed with the following error: '.mysqli_connect_errno();
exit;
}

this is to check if the database is correctly connected, if not then it will show some errors.

$result = mysqli_query($db,$sql);

here i put the database and the sql command to run my query.

while($row = mysqli_fetch_array($result)){
      echo $row['username'];
}

here finally outputting the usernames(username is one of the column in my table in this case) which matched with that query i will suggest This Sql site to get a better understanding on sql queries and try to improve the secuirty because this is the basic point where hackers try to inject their attact most offenly. Note : If your table's in the database are empty then it will not able to fetch anything
