The web's workhorse

PHP

PHP is a server-side language that powers a large share of the web, from WordPress and Laravel applications to plain templated sites and JSON APIs, and it runs anywhere a web host does. This curriculum starts with the syntax, types, loops, functions and arrays you need for any script, moves on to strings, associative arrays, sorting and classes, and finishes with exceptions and JSON handling, the two skills every real PHP backend depends on. Every example is verified against PHP 8.4, and every exercise reads standard input and prints to standard output, so what you write here works unchanged on the command line.
