Learn PHP and build dynamic, database-driven websites.

Your learning path

Move from variables and functions to request handling, forms, sessions, and data access. Treat every external input as data that needs validation and careful output handling.

Put the lessons into practice

Build a small form handler with clear validation errors. Use prepared statements for database values and escape output for its destination rather than concatenating unchecked input.
