PHP Create MySQL Tables

A database table has its own unique name and consists of columns and rows.


Create a MySQL Table Using MySQLi and PDO

The CREATE TABLE statement is used to create a table in MySQL.
We will create a table named "MyGuests", with five columns: "id", "firstname", "lastname", "email" and "reg_date":

CREATE TABLE MyGuests ( id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, firstname VARCHAR(30) NOT NULL, lastname VARCHAR(30) NOT NULL, email VARCHAR(50), reg_date TIMESTAMP )

Notes on the table above:

The data type specifies what type of data the column can hold. For a complete reference of all the available data types, go to our Data Types reference.
After the data type, you can specify other optional attributes for each column:
  • NOT NULL - Each row must contain a value for that column, null values are not allowed
  • DEFAULT value - Set a default value that is added when no other value is passed
  • UNSIGNED - Used for number types, limits the stored data to positive numbers and zero
  • AUTO INCREMENT - MySQL automatically increases the value of the field by 1 each time a new record is added
  • PRIMARY KEY - Used to uniquely identify the rows in a table. The column with PRIMARY KEY setting is often an ID number, and is often used with AUTO_INCREMENT
Each table should have a primary key column (in this case: the "id" column). Its value must be unique for each record in the table.
The following examples shows how to create the table in PHP:

Example (MySQLi Object-oriented)

<?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 $sql = "CREATE TABLE MyGuests ( id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, firstname VARCHAR(30) NOT NULL, lastname VARCHAR(30) NOT NULL, email VARCHAR(50), reg_date TIMESTAMP )"; if ($conn->query($sql) === TRUE) { echo "Table MyGuests created successfully"; } else { echo "Error creating table: " . $conn->error; } $conn->close(); ?>

Example (MySQLi Procedural)

<?php $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "myDB"; // Create connection $conn = mysqli_connect($servername, $username, $password, $dbname); // Check connection if (!$conn) { die("Connection failed: " . mysqli_connect_error()); } // sql to create table $sql = "CREATE TABLE MyGuests ( id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, firstname VARCHAR(30) NOT NULL, lastname VARCHAR(30) NOT NULL, email VARCHAR(50), reg_date TIMESTAMP )"; if (mysqli_query($conn, $sql)) { echo "Table MyGuests created successfully"; } else { echo "Error creating table: " . mysqli_error($conn); } mysqli_close($conn); ?>

Example (PDO)

<?php $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "myDBPDO"; try { $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password); // set the PDO error mode to exception $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); // sql to create table $sql = "CREATE TABLE MyGuests ( id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, firstname VARCHAR(30) NOT NULL, lastname VARCHAR(30) NOT NULL, email VARCHAR(50), reg_date TIMESTAMP )"; // use exec() because no results are returned $conn->exec($sql); echo "Table MyGuests created successfully"; } catch(PDOException $e) { echo $sql . "<br>" . $e->getMessage(); } $conn = null; ?>
