SQL Server 2019 : PHP から利用する2021/05/30 |
|
PHP からの SQL Server 利用例です。
|
|
| [1] | PHP 7.4 インストール済みを前提として例示します。 追加で必要なパッケージをインストールしておきます。 |
|
[root@dlp ~]# dnf -y install gcc make php-pear php-pdo php-devel [root@dlp ~]# pecl install sqlsrv pdo_sqlsrv [root@dlp ~]# echo 'extension=pdo_sqlsrv.so' > /etc/php.d/99-pdo_sqlsrv.ini [root@dlp ~]# echo 'extension=sqlsrv.so' > /etc/php.d/99-sqlsrv.ini |
| [2] | テスト用のデータベース接続用ユーザーとデータベースを作成しておきます。 |
|
[root@dlp ~]# sqlcmd -S localhost -U SA Password: # ログインユーザー作成 1> create login cent with PASSWORD= N'password'; 2> go # [SampleDB] 作成 1> create database SampleDB; 2> go 1> use SampleDB; 2> go Changed database context to 'SampleDB'. # ログインユーザー [cent] と関連付けて DB ユーザー作成 1> create user cent for login cent; 2> go # [cent] に DB オーナーロール付与 1> exec sp_addrolemember 'db_owner', 'cent'; 2> go # テストテーブル作成 1> create table SampleTable ( 2> ID int identity(1,1) not null primary key, First_Name NVARCHAR(50), Last_Name NVARCHAR(50) ); 3> insert into SampleTable ( 4> First_Name, Last_Name) values (N'CentOS', N'Linux'), (N'RedHat', N'Linux'), (N'Fedora', N'Linux' ); 5> go |
| [3] | 基本的な利用例です。データベースや接続ユーザーは上記で作成したものを使用します。 |
