实例讲解通过​PHP创建数据库

<?php

 header("Content-Type: text/html; charset=utf8");

$servername = "localhost";

$username = "username"

$password = "password"

//创建链接

$conn = new mysqli($servername,$username,$password);

if($conn->connect_error){

  die("连接失败" .$conn->connect_error);

}

//创建一个为newDemo的数据库

$sql = "CREATE DATABASE newDemo";

//mysqli_query() 函数用于执行某个针对数据库的查询。

if($conn->query($sql) === TRUE){

 

  echo "数据库创建成功";

}

else {

  echo "Error creating database: " . $conn->error;

}

//关闭数据库

$conn->close();

?>
