php-mysqlHow to create a table in a MySQL database using PHP?

Creating a table in a MySQL database using PHP is a simple process. The following example code block will create a table called users with three columns: id, name, and email:

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

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// sql to create table
$sql = "CREATE TABLE users (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(30) NOT NULL,
email VARCHAR(50),
reg_date TIMESTAMP
)";

if ($conn->query($sql) === TRUE) {
    echo "Table users created successfully";
} else {
    echo "Error creating table: " . $conn->error;
}

$conn->close();
?>

The output of the example code will be:

Table users created successfully

Code explanation

1. $servername, $username, $password, $dbname: These variables are used to store the connection information for the MySQL database.
2. $conn = new mysqli($servername, $username, $password, $dbname): This line creates a new connection to the MySQL database using the connection information stored in the variables.
3. $sql = "CREATE TABLE users (...): This line creates a SQL query to create a table called users with three columns: id, name, and email.
4. if ($conn->query($sql) === TRUE): This line executes the SQL query to create the table.
5. echo "Table users created successfully": This line prints a message to the screen if the table was created successfully.
