Knowledge about PHP, web development and automation

How are web applications built? What does an API do? When is a process worth automating? We explain technical foundations and practical development decisions, with clear guidance for businesses and useful detail for developers.

A note on language

The articles themselves are written in German. We publish what has been written and professionally reviewed rather than running thirty-one texts through a translation that nobody has checked — a technical article that is subtly wrong is worse than one you have to read in another language.

If a particular topic matters to you and German is a barrier, write to us. We will answer your question directly, and if it comes up repeatedly, that is a good reason to translate the article properly.

How these texts are written

Every article states its audience, its level and when it was written. Examples are marked as examples and assumptions as assumptions. Where official sources exist, we link to them rather than to a summary.

What you will not find: invented market prices, estimated savings presented as a promise, or articles that fill a headline with search terms.
