Requirements

The PHP variant of the driver requires PHP 5.4 or higher.

The HHVM variant of the driver requires HHVM 3.9 or higher.

The driver requires » libbson and » libmongoc, and will use bundled versions of both libraries by default.

The driver requires » OpenSSL and will rely on PHP to find its headers (i.e. PHP_SETUP_OPENSSL). If the build process fails to find OpenSSL, check that the OpenSSL development package (e.g. libssl-dev) and » pkg-config are both installed.

» Cyrus SASL is an optional dependency and will be used if available.
