- Markdown files under
tutorials/are the readable editions maintained by this repository. - Files under
tutorials/src/preserve the HTML or text sources used to create those editions. Keep these snapshots intact when making readability or link repairs. - Historical tutorials may contain obsolete commands, dependencies, hostnames, and version-specific advice. The README labels these documents as historical rather than silently presenting them as current guidance.
- Built-in function documentation in the updated manual was formatted after the style of language-reference sites such as PHP.net.
