Requirements

As of version 1.8.0, the driver requires PHP 7.0 or higher. Previous versions of the driver allow compatibility with older PHP versions.

The driver requires » libbson and » libmongoc, and will use bundled versions of both libraries by default. System libraries may also be used, as discussed in the manual installation documentation.

The driver, via libmongoc, optionally depends on a TLS library (e.g. OpenSSL) and will use it if available. If the build process fails to find a TLS library, users should check that the appropriate development package (e.g. libssl-dev) and » pkg-config are both installed. The process for detecting and configuring TLS libraries is discussed in more detail in the manual installation documentation.

» Cyrus SASL is an optional dependency to support Kerberos authentication and will be used if available.

Note: Due to potential problems representing 64-bit integers on 32-bit platforms, users are advised to use 64-bit environments. When using a 32-bit platform, be aware that any 64-bit integer read from the database will be returned as a MongoDB\BSON\Int64 instance instead of a PHP integer type.
