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, andforeach.
- Common types include
Functions and Arrays
- PHP utilizes functions to organize code into reusable blocks and supports arrays for managing collections of data.
