The PsySH doc command is great for documenting source code, but you’ll need a little something extra for PHP core documentation. Download one of the following PHP reference manual files and drop it in ~/.local/share/psysh/, /usr/local/share/psysh/ or %APPDATA%\PsySH\ on Windows.

• English
• Brazilian Portuguese
• Chinese (Simplified)
• French
• German
• Italian
• Japanese
• Romanian
• Russian
• Spanish
• Turkish

The PHP Manual has about 25 other translations. If you speak a language not on the list above, chances are high that someone has already started a translation, but for various reasons it’s no longer being updated. If you’d like to see doc support in another language, check out PHP.net for information on helping translate a specific language.

You can also try your hand at building the manual for an unsupported language in its current state, but please keep the following caveat in mind:

All of these translations are out of date, and their content is likely wrong or insecure.
