I want to create a class which uses PDO to interact with MySQL. Can I create a new MySQL table using PDO?
Yes, you can.
The dsn
part, which is the first parameter of the PDO constructor, does not have to have a database name. You can simply use mysql:host=localhost
. Then, given you have the right privilege, you can use regular SQL commands to create a database and users, etc.
Following is an example from an install.php file. It logs in with root, create a database, a user, and grant the user all privilege to the new created database:
<?php
$host = "localhost";
$root = "root";
$root_password = "rootpass";
$user = 'newuser';
$pass = 'newpass';
$db = "newdb";
try {
$dbh = new PDO("mysql:host=$host", $root, $root_password);
$dbh->exec("CREATE DATABASE `$db`;
CREATE USER '$user'@'localhost' IDENTIFIED BY '$pass';
GRANT ALL ON `$db`.* TO '$user'@'localhost';
FLUSH PRIVILEGES;")
or die(print_r($dbh->errorInfo(), true));
}
catch (PDOException $e) {
die("DB ERROR: " . $e->getMessage());
}
?>
Yes, it's the same, like running a regular query like "CREATE TABLE ...".
