    • The presentation covered web platform development, outlining topics like client-server architecture, web server architecture, LAMP setup, HTML5, CSS3, and PHP.
    • It also discussed web developer constraints, comparing web programming to general programming, and software as a service.

    Client-Server Architecture

    • Client-server architecture is a computing model where the server manages resources and services consumed by the client.
    • The web utilizes this architecture.
    • The client makes requests, and the server delivers the resources.

    Static HTML

    Dynamic HTML

    Client-Side Programming

    • HTML defines webpage content (text, images, sounds).
    • CSS styles the HTML webpage.
    • JavaScript handles dynamic client-side actions.

    Server-Side Programming

    • Server-side programming languages include PHP, Python, Java, and .NET.
    • Frameworks are optional collections of packages that assist developers in building web applications or services more efficiently.
    • Conventions within frameworks streamline development.

    Server-side Webserver

    • A webserver manages client HTTP requests.
    • Examples of webservers include Apache, nginx, and Kestrel.

    Database

    • Databases are used for data storage.
    • Examples include MySQL, Excel, and Oracle.

    LAMP Stack

    • LAMP (Linux, Apache, MySQL, PHP) comprises a stack for generating dynamic web pages on Linux.
    • There's also WAMP.
    • Key components include:
      • Linux (web server operating system).
      • Apache (web server handling HTML requests).
      • MySQL (relational database).
      • PHP (dynamic HTML).

    Why LAMP?

    • Linux/Unix is a prevalent server operating system (70%+)
    • Apache is a widely used web server (30%+).
    • PHP ranks highly as a web development language (78%).
    • LAMP benefits from being an open-source platform.

    Linux

    • Ubuntu is a user-friendly Linux distribution.
    • Other popular distributions include Debian, Fedora, CentOS, and commercial options like Red Hat and SUSE.

    Basic Apache Setup

    • Apache is a cross-platform web server.
    • Steps include opening a terminal and installing Apache2 using sudo apt install apache2.
    • Check the installation by opening a web browser and navigating to http://localhost.

    PHP Setup

    • To install PHP on Ubuntu, use sudo apt install php libapache2-mod-php

    HTML Introduction

    • HTML (HyperText Markup Language) is used to structure webpages.
    • Visit https://www.w3schools.com/html/ for HTML documentation.
    • A webpage is required for displaying HTML.

    HTML Editors

    • HTML can be created with various editors:
      • Text editors (Notepad++, Komodo IDE, UltraEdit).
      • WYSIWYG editors (DreamWeaver, PhpStorm).
      • Templates (Google sites, Facebook, eBay, Shopee).

    PhpStorm

    • PhpStorm is an IDE provided by JetBrains, offering free education licenses.
    • Features include code suggestions, real-time error checking, and browser shortcuts.

    Warning

    • Replicating examples from other sources may lead to problems related to quote variation.
    • Ensure the double quotes are correct in code.

    A HTML page

    • A basic HTML page comprises elements, attributes, and their values.
    • HTML elements are case insensitive, using lowercase consistently.
    • <!DOCTYPE> isn't an HTML tag but declares the document type.

    Creating a HTML page with PhpStorm

    • Steps include creating a new project in PhpStorm and selecting "HTML" as the project type or creating a new file.

    Basic HTML Elements

    • The html element encapsulates the entire HTML document.
    • The head section contains metadata (e.g., title, language).
    • The body section contains the webpage content.

    Basic HTML Elements (continued)

    • HTML elements accept attributes that modify their behavior or appearance.

    Common HTML Elements

    • Various elements (e.g., <a>, <br>, <div>, <form>, <h1>-<h6>, <hr>, <img>, <input>, <link>, <p>, <script>, <span>) perform different functions.

    HTML Lists and Table Elements

    • List elements (<li>, <ol>, <ul>) organize information.
    • Table elements (<table>, <tr>, <td>, <th>) structure data.

    CSS

    • CSS (Cascading Style Sheets) is used to format webpages.
    • Using CSS allows for more control and organization in styling compared to modifying element attributes directly.

    Style Attribute

    • Inline styling utilizing the style attribute modifies a single element's appearance.
    • Attributes include properties such as color and font weight, applied directly to a specific element within a style="..." attribute.

    Internal Style Sheet

    • Internal CSS styles affect an entire HTML page.
    • The style tags are included in the <head> section of the HTML, making the styles applicable to the entire document.

    External Style Sheet

    • External CSS enhances style consistency across multiple files, applying them uniformly to multiple pages.
    • An external CSS stylesheet file is linked to an HTML document using the <link> tag, typically located within the <head> section of the document.

    id Global Attribute

    • Use a unique ID (<div id="uniqueID">) to apply styles to a specific element.

    class Global Attribute

    • The class attribute (<div class="uniqueClass">) dynamically employs styles.
    • Similar styles can be applied across many HTML elements.

    Font

    • The font-family property defines the default font for a webpage.
    • Setting multiple font styles ensures the webpage can fall back to an appropriate font if the first one isn't available.

    Border

    • HTML elements' borders can be customized using the border property, adjusting thickness, style, and color in a specific order.

    List

    • The default list style can be customized via list-style-type options (e.g., circle, decimal, disc, none, square, upper-roman).

    Background

    • Background images can be applied by specifying the background-image property.
    • The background-repeat and background-position properties control the background's image repetition and location.

    Layout

    • Use <div> elements with CSS properties like float, width, padding, and margin for webpage layout design.

    Headers and Footers

    • The header and footer elements hold site information, such as menubars and copyright notices respectively.

    PHP

    • PHP (Hypertext Preprocessor) is a server-side scripting language used to create dynamic web content.
    • PHP files typically contain HTML, CSS, JavaScript, and PHP code, making them versatile for web development.

    PHP Beginner

    • PHP is a case-sensitive scripting language.
    • The start tag is <?php and the end tag is ?>.
    • Variables should be declared in code when performing variable assignment.

    PHP: Hello World! - info function

    • The phpinfo() function displays comprehensive configuration information, crucial for debugging and troubleshooting PHP installations and dependencies.

    PHP with PhpStorm

    • Integrating PHP into PhpStorm involves configuring a PHP interpreter; the user must ensure their operating system has a PHP interpreter available.

    PHP: Frequent Used Functions

    • printf() is a versatile function used to format and display various data types, such as numbers, and text with additional formatting elements.
    • Different conversion specifiers control how different types of data that are input are formatted, output, and displayed within the webpage.

    PHP: Basic PHP

    • Explains commenting conventions in PHP (multiline comments).
    • Demonstrates types of variable assignment (numeric, string, and array).

    PHP: Operators

    • PHP includes different types of operators for performing various operations (arithmetic, assignment, comparison, logical, etc), making it crucial for various programming tasks within a webpage.

    PHP: Control Statement and Loops

    • Explains conditional statements (if/elseif/else) and loops (while) that govern the flow of execution based on conditions and iterations, respectively, in PHP statements.
    • Demonstrates how conditions in PHP programming statements can be manipulated through the use of loops and if/else statements.

    PHP: Functions and Objects

    • Explains function declarations, demonstrating how to define reusable blocks of code.
