Installing PHPThemis #

PHPThemis is available as a system package for Linux. Usually you want to install the stable package to benefit from automatic dependency management and security updates. However, you can also build and install the latest PHPThemis from the source code.

Building latest version from source #

If the stable package version does not suit your needs, you can manually build and install the latest version of Themis from source code.

Build and install Themis Core library into your system.
