SQL Server 2019 : Use with PHP2021/05/30

	This is an example to use SQL Server with PHP.
[1]	This is based on the environment PHP 7.4 has been installed. Additionally, Install other required packages.

[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]	Create a sample User and Database for Test.

[root@dlp ~]#

sqlcmd -S localhost -U SA

Password:

# create login user
1> create login cent with PASSWORD= N'password';
2> go

# create [SampleDB]
1> create database SampleDB;
2> go

1> use SampleDB;
2> go
Changed database context to 'SampleDB'.

# create DB user
1> create user cent for login cent;
2> go

# assign DB owner role to [cent]
1> exec sp_addrolemember 'db_owner', 'cent';
2> go

# create [SampleTable]
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]	These are some basic usage to connect to SQL Server with PHP.
