How to create a MySQL table through PHP
How to create a mysql table through php. This article will explain in detail how to create a mysql table through php.
Creating a MySQL table using MySQLi and PDO
The CREATE TABLE statement is used to create a MySQL table.
Before creating the table, we need to use use myDB to select the database to operate:
use myDB;
We will create a table named "MyGuests" Table, with 5 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 )
Data typeSpecifies what type of data the column can store. For complete data types please refer to our Data Types Reference Manual.
After setting the data type, you can specify the properties of other options for each column:
NOT NULL - Each row must contain a value (cannot be empty), the null value is not Allowed.
DEFAULT value - Set the default value
UNSIGNED - Use unsigned numeric type, 0 and positive numbers
AUTO INCREMENT - Set the value of the MySQL field every time when adding a record Automatically increase 1 times
PRIMARY KEY - Set the unique identification of each record in the data table. Typically the column's PRIMARY KEY is set to the ID value, used with AUTO_INCREMENT.
Each table should have a primary key (this column is the "id" column), and the primary key must contain a unique value.
The following example shows how to create a table in PHP:
Example (MySQLi - Object-oriented)
<?php$servername = "localhost";$username = "username";$password = "password";$dbname = "myDB";// 创建连接$conn = new mysqli($servername, $username, $password, $dbname);// 检测连接if ($conn->connect_error) { die("连接失败: " . $conn->connect_error);} // 使用 sql 创建数据表$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 "创建数据表错误: " . $conn->error;}$conn->close();?>
实例 (MySQLi - 面向过程)
<?php$servername = "localhost";$username = "username";$password = "password";$dbname = "myDB";// 创建连接$conn = mysqli_connect($servername, $username, $password, $dbname);// 检测连接if (!$conn) { die("连接失败: " . mysqli_connect_error());}// 使用 sql 创建数据表$sql = "CREATE TABLE MyGuests (id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, firstname VARCHAR(30) NOT NULL,lastname VARCHAR(30) NOT NULL,email VARCHAR(50),reg_date TIMESTAMP)";if (mysqli_query($conn, $sql)) { echo "数据表 MyGuests 创建成功";} else { echo "创建数据表错误: " . mysqli_error($conn);}mysqli_close($conn);?>
实例 (PDO)
<?php$servername = "localhost";$username = "username";$password = "password";$dbname = "myDBPDO";try { $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password); // 设置 PDO 错误模式，用于抛出异常 $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); // 使用 sql 创建数据表 $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 )"; // 使用 exec() ，没有结果返回 $conn->exec($sql); echo "数据表 MyGuests 创建成功";}catch(PDOException $e){ echo $sql . "<br>" . $e->getMessage();}$conn = null;?>This article explains PHP in detail For the operation of creating a data table, please pay attention to the php Chinese website for more learning materials.
