Let’s first take a look at the fields to be stored in our database

We will store the information in the above picture into the database

• Name

• ageage

• gender sex

• Class class

Now that we know the fields to be stored, let’s create our database first

Create database

<?php
header("Content-type:text/html;charset=utf-8");    //設置編碼
$servername = "localhost";
$username = "root";
$password = "root";
// 創(chuàng)建連接
$conn = mysqli_connect($servername, $username, $password);
mysqli_set_charset($conn,'utf8'); //設定字符集
// 檢測連接
if (!$conn) {
    die("連接失敗: " . mysqli_connect_error());
}
// 創(chuàng)建數(shù)據(jù)庫
$sql = "CREATE DATABASE study";
if (mysqli_query($conn, $sql)) {
    echo "數(shù)據(jù)庫創(chuàng)建成功";
} else {
    echo "數(shù)據(jù)庫創(chuàng)建失敗: " . mysqli_error($conn);
}
mysqli_close($conn);
?>

The above code creates a database named "study"

Create data table

A 'stu' table was created in the "study" database

<?php
header("Content-type:text/html;charset=utf-8");    //設置編碼
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "study";
// 創(chuàng)建連接
$conn = mysqli_connect($servername, $username, $password, $dbname);
mysqli_set_charset($conn,'utf8'); //設定字符集
// 檢測連接
if (!$conn) {
    die("連接失敗: " . mysqli_connect_error());
}
// 使用 sql 創(chuàng)建數(shù)據(jù)表
$sql = "CREATE TABLE stu (
 id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
 name VARCHAR(50) NOT NULL,
 age INT(6) NOT NULL,
 sex VARCHAR(20),
 class VARCHAR (50) NOT NULL
 );";
if (mysqli_query($conn, $sql)) {
    echo "數(shù)據(jù)表 stu 創(chuàng)建成功";
} else {
    echo "創(chuàng)建數(shù)據(jù)表錯誤: " . mysqli_error($conn);
}
mysqli_close($conn);
?>
