PHP MySQL Database

In the previous tutorial, we create PHP Connection To MySQL. For this follow-up tutorial, I decided to make a tutorial on How To Create MySQL Database. For creating a database, it will consist one or more tables in one database. We create a database and name it as “myDatabase”.

Creating MySQL Database Using MySQLi and PDO

Example database name "myDatabase". Example MySQLi Object-Oriented

<?php
$servername = "localhost";
$username = "username";
$password = "password";
 
// Create connection
$conn = new mysqli($servername, $username, $password);
// Check connection
if ($conn->connect_error) {
    die("Connection Error. Check your syntax." . $conn->connect_error);
} 
 
// Create database
$sql = "CREATE DATABASE myDatabase";
if ($conn->query($sql) === TRUE) {
    echo "Successfully Created The Database";
} else {
    echo "Error creating database. Check the Syntax." . $conn->error;
}
 
$conn->close();
?>

Example database name "myDatabase". Example MySQLi Procedural

<?php
$servername = "localhost";
$username = "username";
$password = "password";
 
// Create connection
$conn = mysqli_connect($servername, $username, $password);
// Check connection
if (!$conn) {
    die("Connection Error. Check your syntax." . mysqli_connect_error());
}
 
// Create database
$sql = "CREATE DATABASE myDatabase";
if (mysqli_query($conn, $sql)) {
    echo "Successfully Created The Database";
} else {
    echo "Error creating database. Check the Syntax." . mysqli_error($conn);
}
 
mysqli_close($conn);
?>

Example database name "myDatabase". Example PDO (PHP Data Objects)

<?php
$servername = "localhost";
$username = "username";
$password = "password";
 
try {
    $conn = new PDO("mysql:host=$servername;dbname=myDatabase", $username, $password);
    // set the PDO error mode to exception
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $sql = "CREATE DATABASE myDatabase";
    // use exec() because no results are returned
    $conn->exec($sql);
    echo "Successfully Created The Database<br>";
    }
catch(PDOException $e)
    {
    echo $sql . "<br>" . $e->getMessage();
    }
 
$conn = null;
?>

I use PHPMyAdmin to create a database in MySQL. After creating my database in PHPMyAdmin, this is my query using PDO in shortcodes.

<?php
$conn = new PDO("mysql:host=localhost;dbname=myDatabase", 'username', 'password');
?>
