How to install php

Php is developer utility. Treat this as an orientation note. Anything prescriptive should come from the maintainers directly.

Distribution in practice

Expect differences between platforms. The same project may reach one system through a package index and another through a source build.

Who is behind it

The project is self-governed. Whoever maintains it chooses what ships and when, and writes the accompanying material.

First things to confirm

Check platform support first. Recent work in this space generally assumes a current runtime and a reasonably modern system.

Making sense of the result

If the outcome is not what was expected, the cause is nearly always environmental: an earlier copy, a different channel, or a cache that has not been refreshed.

About these notes

These pages exist as notes. No files are hosted, and no project material is reproduced on this domain.

Where things commonly go wrong

The most frequent surprise is a version that resolves somewhere unexpected. Check which copy is actually being picked up before assuming the project itself misbehaves.
