SQL Server 2022 : PHP から利用する2023/12/15

	PHP からの SQL Server 利用例です。
[1]	PHP 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:~#

apt -y install gcc make php-pear php-pdo php-dev

root@dlp:~#

pecl install sqlsrv pdo_sqlsrv

root@dlp:~#

echo 'extension=pdo_sqlsrv.so' > /etc/php/8.2/mods-available/pdo_sqlsrv.ini

root@dlp:~#

echo 'extension=sqlsrv.so' > /etc/php/8.2/mods-available/sqlsrv.ini

root@dlp:~#

phpenmod pdo_sqlsrv

root@dlp:~#

phpenmod sqlsrv

[2]	基本的な利用例です。データベースや接続ユーザーは事前に適当に作成したものを使用します。
