Install PHP drivers for Microsoft SQL Server on Ubuntu PHP 7.2

On Ubuntu 18.04 server running PHP 7.2, i want to install Microsoft SQL Server module for PHP. You can find PHP module for SQL server at

https://github.com/microsoft/msphpsql

At the time of writing this PHP module only support PHP 7.4 and newer. SO i need to find older version that supported PHP 7.2. On checking release page, i found version 5.8.0 supported PHP 7.2

First install php7.2 dev package with

apt install php7.2-dev

Instal php modules with pcel

pecl install sqlsrv-5.8.0

During install, i got error

config.status: creating config.h

This is fixed with command

apt-get install unixodbc-dev

install pdo_sqlsrv with

pecl install pdo_sqlsrv-5.8.0

Run

printf "; priority=20\nextension=sqlsrv.so\n" > /etc/php/7.2/mods-available/sqlsrv.ini
printf "; priority=30\nextension=pdo_sqlsrv.so\n" > /etc/php/7.2/mods-available/pdo_sqlsrv.ini

Enabe PHP modules with

phpenmod -v 7.2 sqlsrv pdo_sqlsrv

Restart Apache, now phpinfo() shows pdo_sqlsrv

But when accessing PHP script that connect to MS SQL server, i get error

This extension requires the Microsoft ODBC Driver for SQL Server to communicate with SQL Server. Access the following URL to download the ODBC Driver for SQL Server for x64

To fix this, do

curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add -

For Ubuntu 16.04

curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list > /etc/apt/sources.list.d/mssql-release.list

For Ubuntu 18.04

curl https://packages.microsoft.com/config/ubuntu/18.04/prod.list > /etc/apt/sources.list.d/mssql-release.list

For Ubuntu 20.04

curl https://packages.microsoft.com/config/ubuntu/20.04/prod.list > /etc/apt/sources.list.d/mssql-release.list

Ubuntu 20.10

curl https://packages.microsoft.com/config/ubuntu/20.10/prod.list > /etc/apt/sources.list.d/mssql-release.list

Update apt cahe

apt-get update

Install Microsoft ODBC

apt-get install -y msodbcsql17

Optional: for bcp and sqlcmd

apt-get install -y mssql-tools
echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bashrc
source ~/.bashrc
apt-get install -y unixodbc-dev

Now php MS SQL module will work. You can find sample PHP code at
