How do I install PHP?

Usually PHP is installed alongside Apache and MySQL in a combination known as AMP, see Installing AMP for details. It is possible to build PHP from source - you might have to if you need a very new version for developing Moodle - however, it is quite challenging. PHP itself has many dependencies that you will need to obtain and build, some of which are also tricky to build from source (e.g. GD).
