    php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
    php -r "if (hash_file('SHA384', 'composer-setup.php') === '669656bab3166a7aff8a7506b8cb2d1c292f042046c5a994c43155c0be6190fa0355160742ab2e1c88d40d5be660b410') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
    php composer-setup.php
    php -r "unlink('composer-setup.php');"
    
## 2. Install PHPBench

Navigate into Performance folder. Create the following `composer.json` file within it:

    {
        "name": "Benchmark - PHP Drivers for SQL Server",
        "require-dev": {
            "phpbench/phpbench": "^1.0@dev"
        },
        "autoload": {
            "psr-4": {
                "SqlsrvPerfTest\\": "lib",
                "PDOSqlsrvPerfTest\\": "lib"
            }
        }
    }
    
Create `phpbench.json` in the same folder. 

    {
        "bootstrap": "vendor/autoload.php"
    }
