Answer 1

I think you want something like this if you use MySQL :
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT username, email FROM MyTable";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "username: " . $row["username"]. " - email: " . $row["email"]. "<br>";
}
} else {
echo "0 results";
}
$conn->close();
?>
In my opinion you're probably a beginner with web development with databases.
I recommend you w3chools. You can reed various examples in this site:

Your question is not clear, but if you are new with database I recommend you to start with PDO instead of mysqli.
<?php
//Db connection
function pdo_connect_mysql() {
$DATABASE_HOST = 'localhost';
$DATABASE_USER = 'root';
$DATABASE_PASS = '';
$DATABASE_NAME = 'phpcrud';
try {
return new PDO('mysql:host=' . $DATABASE_HOST . ';dbname=' . $DATABASE_NAME . ';charset=utf8', $DATABASE_USER, $DATABASE_PASS);
} catch (PDOException $exception) {
// If there is an error with the connection, stop the script and display the error.
exit('Failed to connect to database!');
}
}
// User Input
$username = 'john';
$email = 'john#gmail.com';
$sql = 'SELECT * FROM register WHERE username = ? email = ?';
$stmt = pdo_connect_mysql() ->prepare($sql);
$stmt->execute([$username, $email]);
$register = $stmt->fetchAll();
?>
