Overview of web development knowledge

Knowing how to create a website and then take comprehensive care of it is not just a matter of making it. There are many hurdles along the way and it's good to have at least a basic idea of each thing. When I started out, I didn't really know what all there was to learn. This page serves as a signpost through the topics I had to study gradually to be able to understand web development and deal with most common situations.

Server administration

A web server is a computer that runs the web. When a user views a page, the web server sends the page to the user.

At the moment (2021), it no longer makes sense to get free hosting if you are serious about the web. A server can be rented from 50 crowns per month.

• Server installation (differs on Windows and Linux)
• Server configuration
• Apache settings
• PHP setup
• getting the current PHP configuration (function phpinfo())
• Ngnix routing (improves server performance)

Internet and web browser

• Web browsers
• Request & response principle
• URL address
• Ajax and Ajaj
• HTML code generation (templating systems)

Strings

• Reading, writing and concatenating strings, especially basic string work
• Processing strings
• Browsing character by character
• comparing strings
• String similarity (functions levenshtein(), similar_text() and soundex())
• Explode, splitting by separator
• Regular expressions split strings according to a universally configurable mask
• Tokenizer breaks strings into small parts (tokens)
• Serialization of data into a string
• Json, a javascript object stored in a string
