有没有一种方法可以使用PHP创建一个新的MySQL数据库，一个新的MySQL用户，并将新用户赋予对新数据库的权限？

你可以像这样做：
mysql_connect('localhost','user',password);
mysql_query("CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';");
mysql_query("GRANT ALL ON db1.* TO 'username'@'localhost'");
mysql_query("CREATE DATABASE newdatabase");
mysql_close();
您可以查看MySQL文档关于GRANT和CREATE USER的内容。

使用PHP 7中的mysqli
<?php
$conn = mysqli_connect('localhost','root','','test');
mysqli_query($conn, "CREATE DATABASE newdatabase");
mysqli_query($conn, "CREATE USER 'dynauser'@'localhost' IDENTIFIED BY 'dynapassword';");
mysqli_query($conn, "GRANT SELECT, INSERT, UPDATE, DELETE ON newdatabase3.* TO 'dynauser'@'localhost'");
mysqli_close($conn); - Kamlesh

是的，所有这些操作都可以通过常规的SQL查询来执行。
然而，我会避免使用root用户运行带有数据库连接的PHP脚本。

7使用一个专门的账户来创建数据库和用户，这个账户只有这个权限可以防止意外情况的发生，同时如果这个账户被攻击也可以限制损失。这个账户无法删除任何内容，也无法访问数据。 - Dan Blows

如果您将项目托管在CPanel上，则
从这里下载xmlapi.php，或者在谷歌上搜索它。
这对我完美地起作用了。
mysql_query方法无法用于创建数据库、用户和授予权限。您必须使用CPanel的XML API。<?php
include("xmlapi.php");
$db_host = 'yourdomain.com';
$cpaneluser = 'your cpanel username';
$cpanelpass = 'your cpanel password';
$databasename = 'testdb';
$databaseuser = 'test'; // Warning: in most of cases this can't be longer than 8 characters
$databasepass = 'dbpass'; // Warning: be sure the password is strong enough, else the CPanel will reject it
$xmlapi = new xmlapi($db_host);
$xmlapi->password_auth("".$cpaneluser."","".$cpanelpass."");
$xmlapi->set_port(2082);
$xmlapi->set_debug(1);//output actions in the error log 1 for true and 0 false
$xmlapi->set_output('array');//set this for browser output
//create database
$createdb = $xmlapi->api1_query($cpaneluser, "Mysql", "adddb", array($databasename));
//create user
$usr = $xmlapi->api1_query($cpaneluser, "Mysql", "adduser", array($databaseuser, $databasepass));
//add user
$addusr = $xmlapi->api1_query($cpaneluser, "Mysql", "adduserdb", array("".$cpaneluser."_".$databasename."", "".$cpaneluser."_".$databaseuser."", 'all'));
?>

数据库已成功创建，用户也已成功创建，但新创建的用户尚未分配到数据库中。 - user2092434

我建议您使用phpMyAdmin。
您需要执行以下步骤：
如果您想了解更多关于phpMyAdmin的信息，请前往官方网站。
但如果有任何特殊原因需要使用PHP，则可以使用以下SQL命令。
您需要执行以下步骤：
- 打开phpMyAdmin
- 进入管理部分
- 点击添加用户账户
- 输入用户名和密码
- 设置权限
- 点击 [ Go ] 按钮
如果您想了解更多关于phpMyAdmin的信息，请前往官方网站。
但如果有任何特殊原因需要使用PHP，则可以使用以下SQL命令。
CREATE USER 'tesrytss'@'%'//user name
IDENTIFIED VIA mysql_native_password USING '***';.//set pass
GRANT SELECT, INSERT, UPDATE, DELETE, FILE ON *.* TO 'tesrytss'@'%' // previlages and username and location
REQUIRE NONE WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0; //other requerment

打开PHP MyAdmin或MySql Workbench，进入查询窗口，然后运行以下查询
CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
GRANT ALL ON db1.* TO 'username'@'localhost'"
