Here is a full summary of the key concepts organised by unit: UNIT 1: Introduction to Compiler Compiler and its Phases A compiler is a translator that converts high-level language (HLL) into machine language. Its main goal is to transform code without changing its meaning and to report errors. Compilation executes in two parts: translating the source program into an object program (low-level language), and then translating the object program into the target program using an assembler. The compilation process involves six main phases: Lexical Analysis (Scanner): Reads source code character-by-character, converting it into meaningful lexemes and re...

Module I: PHP and Web Development Fundamentals PHP Basics : Introduces PHP as an interpreted, server-side scripting language embedded in HTML. It covers fundamental concepts like variable declaration (using the $ sign), data types (integers, doubles, booleans, strings, etc.), and basic syntax. Core Programming Constructs : Detailed explanations and examples of arrays (indexed, associative, multidimensional), operators (arithmetic, comparison, logical, assignment), and control structures like if , elseif , else , and switch . Advanced PHP Features : Covers functions, file handling (opening, reading, writing, and deleting files), and handling web form data using GET and POST met...
