    Study Notes

    Server-Side Scripting

    • Refers to scripts that execute on a web server, generating dynamic web content.
    • Unlike client-side scripts, server-side scripts are processed before reaching the user’s browser.
    • Key operations include accessing databases, processing form data, and customizing user content.
    • Examples of server-side scripting languages: PHP, Node.js, Python (Django/Flask), Ruby on Rails.

    Overview of PHP

    • PHP (Hypertext Preprocessor) is a popular open-source server-side scripting language tailored for web development.
    • PHP can be embedded directly in HTML and is executed on the server, generating HTML for client browsers.
    • Widely used for dynamic and interactive websites such as e-commerce platforms (e.g., Amazon, Shopee) and CRM systems (e.g., HubSpot).
    • Supports various platforms including Windows, Linux, and macOS; operates as interpreted, loosely typed, and dynamically typed.

    Setting Up a Local Development Environment

    • To develop with PHP, set up a local server using packages like XAMPP, WAMP, or MAMP.
    • Editors/IDEs such as VS Code, Sublime Text, or PhpStorm can be chosen for coding.
    • PHP scripts should be placed in designated directories (e.g., "htdocs" for XAMPP) and accessed via http://localhost/your-script.php.

    Writing and Running Basic PHP Scripts

    • Save PHP files (e.g., hello.php) in the local server directory and access through a web browser.
    • Example output for a simple script: "Dangal Greetings!"

    PHP Syntax and Embedding PHP in HTML

    • PHP scripts are executed on the server and the output is returned as plain HTML.
    • Basic constructs include PHP tags and output functions like echo.
    • Embedding PHP in HTML allows dynamic content generation based on user interaction.

    Variables, Data Types, and Operators

    • PHP variables start with $ followed by the variable name; names must begin with a letter or underscore.
    • Data types include:
      • String: sequence of characters (e.g., "Dangal Greetings!")
      • Integer: whole numbers (e.g., 42)
      • Float: decimal numbers (e.g., 3.14)
      • Boolean: true/false
      • Array: ordered value collection (e.g., array(1, 2, 3))
      • Object: instance of a class
      • NULL: represents a variable with no value.
    • Operators include arithmetic (+, -, *, /, %), assignment (=, +=, -=), and comparison (==, ===, !=, !==).

    Control Structures: IF, ELSE, SWITCH

    • Control structures dictate program flow based on conditions:
      • if statement: Executes code block if condition is true.
      • if-else statement: Executes one block of code if true, another if false.
      • elseif statement: Checks multiple conditions sequentially.
      • switch statement: Compares a single variable against multiple values, allowing for cleaner code than multiple if-else statements.

    PHP Loop Structures

    • Loops allow for repetitive execution of code:
      • Common types include for, while, do...while, and foreach.

    Functions and Arrays

    • PHP utilizes functions to organize code into reusable blocks and supports arrays for managing collections of data.
