SQL Server 2017 : PHP で利用する2017/10/28 |
|
PHP からの SQL Server 利用例です。
|
|
| [1] | PHP 7.0 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。 |
|
# Remiからインストール [root@dlp ~]# yum --enablerepo=remi-safe -y groups install php70-php-pear php70-php-mbstring php70-php-pdo php70-php-devel [root@dlp ~]# yum -y groups install "Development Tools" [root@dlp ~]# pecl install sqlsrv pdo_sqlsrv [root@dlp ~]# echo 'extension=pdo_sqlsrv.so' > /etc/opt/remi/php70/php.d/30-pdo_sqlsrv.ini [root@dlp ~]# echo 'extension=sqlsrv.so' > /etc/opt/remi/php70/php.d/30-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。 |
|
[cent@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> ); 4> insert into SampleTable ( 5> First_Name, Last_Name) values (N'CentOS', N'Linux'), (N'RedHat', N'Linux'), (N'Fedora', N'Linux' 6> ); 7> 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。 |
