Installing Brew
```
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
```
Installing MSSQL Tools
```
brew tap microsoft/mssql-release https://github.com/Microsoft/homebrew-mssql-release
brew update
brew install msodbcsql17 mssql-tools
```
If you installed this formula with the registration option (default), you'll
need to manually remove [ODBC Driver 17 for SQL Server] section from
odbcinst.ini after the formula is uninstalled. This can be done by executing
the following command:
```
$ odbcinst -u -d -n "ODBC Driver 17 for SQL Server"
```
Install dependencies:
```
$ brew install autoconf automake libtool
```
Install PHP Drivers for MSSQL
```
$ sudo pecl install sqlsrv
$ sudo pecl install pdo_sqlsrv
```
In case your MSSQL `.so` files didn't load properly, you can find the exact location of the files with following command:
```
$ find . -name pdo_sqlsrv.so -print
$ find . -name sqlsrv.so -print
```
In my case I got the following path for the files. Now
```
/usr/local/lib/php/pecl/20170718/sqlsrv.so
/usr/local/lib/php/pecl/20170718/pdo_sqlsrv.so
```
Next, just copy the files to your respective PHP Version lib directory:
```
cp /usr/local/lib/php/pecl/20170718/sqlsrv.so /usr/local/Cellar/php@7.2/7.2.13/lib/php/20170718/
cp /usr/local/lib/php/pecl/20170718/pdo_sqlsrv.so /usr/local/Cellar/php@7.2/7.2.13/lib/php/20170718/
```
Then make sure the following extensions is loaded in `php.ini`
```
extension="pdo_sqlsrv.so"
extension="sqlsrv.so"
```
Use `php -m | grep sqlsrv` to check the extensions is loaded properly.
```
php -m | grep sqlsrv
pdo_sqlsrv
sqlsrv
```
