<?php
$servername = "localhost";
$username = "username";
$password = "password";

// Create connection
$conn = new mysqli($servername, $username, $password);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 
echo "Connected successfully";
?>

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "yourDatabase";

//connect to database
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);


//create table
$sql = "CREATE TABLE TableName (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, 
    column1 VARCHAR(30) NOT NULL,
    column2 VARCHAR(30) NOT NULL,
    column3 VARCHAR(30) NOT NULL,
    reg_date TIMESTAMP
)";

// execute
$conn->exec($sql);



// insert data
$sql = "INSERT INTO TableName (column1, column2, column3)
VALUES ('aaaa', 'bbbb', 'cccc')";

//execute
$conn->exec($sql);
