PHP Create a MySQL Database
A database consists of one or more tables.
You will need special CREATE privileges to create or to delete a MySQL database.
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":
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 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();
?>
Note: When you create a new database, you must only specify the first three arguments to the mysqli object (servername, username and password).
Tip: If you have to use a specific port, add an empty string for the database-name argument, like this: new mysqli("localhost", "username", "password", "", port)
Tip: If you have to use a specific port, add an empty string for the database-name argument, like this: new mysqli("localhost", "username", "password", "", port)
Example (MySQLi Procedural)
<?php
$servername = "localhost";
$username = "username";
$password = "password";
// Create connection$conn = mysqli_connect($servername, $username, $password);
// Check connection if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
// Create database $sql = "CREATE DATABASE myDB";
if (mysqli_query($conn, $sql)) {
echo "Database created successfully";
} else {
echo "Error creating database: " . mysqli_error($conn);
}
mysqli_close($conn);
?>
Example (PDO)
<?php
$servername = "localhost";
$username = "username";
$password = "password";
try {
$conn = new PDO("mysql:host=$servername;dbname=myDB", $username, $password);
// set the PDO error mode to exception $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "CREATE DATABASE myDBPDO";
// use exec() because no results are returned $conn->exec($sql);
echo "Database created successfully<br>";
}
catch(PDOException $e)
{
echo $sql . "<br>" . $e->getMessage();
}
$conn = null;
?>
