Installation on Windows - chung-leong/qb GitHub Wiki

Download the correct QB binary for the version of PHP installed on your system. Choose the thread-safe version if PHP is used in a threaded environment (most likely). Otherwise choose the non-thread-safe version.

Uncompress the package and copy php_qb.dll to the PHP extension folder.

Open php_qb.ini from the installation package. Copy and paste its contents into php.ini. Adjust the configuration directives to suit your needs.

Restart your web server. If you had downloaded the wrong version of the extension, you would see an error message at this point.

Verify that QB is correctly installed in a PHP page that calls phpinfo(). A table containing information about QB should appear. Alternatively, you can check on the command-line by typing <path-to-php>\php –i or -m.
