PHP Create a MySQL Database

To create a MySQL database using PHP, you typically don't use PHP directly for this purpose; instead, you'd use a MySQL client such as phpMyAdmin or the MySQL command-line interface. However, you can use PHP to execute SQL queries that create databases.

Create a MySQL Database Using MySQLi and PDO

The CREATE DATABASE statement is used to create a database in MySQL.
The following examples create a database named "myDB":

Using MySQLi:

<?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);
}

// Create database
$sql = "CREATE DATABASE myDB";
if ($conn->query($sql) === TRUE) {
    echo "Database created successfully";
} else {
    echo "Error creating database: " . $conn->error;
}

$conn->close();
?>

Using PDO:

<?php

$servername = "localhost";
$username = "username";
$password = "password";

try {
    $conn = new PDO("mysql:host=$servername;", $username, $password);
    // set the PDO error mode to exception
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    // Create database
    $sql = "CREATE DATABASE myDB";
    // use exec() because no results are returned
    $conn->exec($sql);
    echo "Database created successfully";
} catch(PDOException $e) {
    echo $sql . "
" . $e->getMessage();
}

$conn = null;
?>
