PHP โ Essential Concepts ๐
1๏ธโฃ Basics of PHP ๐ป
Server-Side Scripting โ PHP runs on the server, generating dynamic web pages. ๐
Syntax & Variables โ $variable_name = "value"; ๐
Data Types โ Strings, Integers, Floats, Booleans, Arrays, Objects. ๐ข
Operators โ Arithmetic (+, -, *, /), Comparison (==, !=), Logical (&&, ||). โโ
2๏ธโฃ Control Structures ๐ ๏ธ
Conditional Statements โ if, else, elseif, switch. ๐
Loops โ for, while, do-while, foreach. ๐
Functions โ Define reusable blocks of code (function myFunction() {}). ๐งฉ
3๏ธโฃ Working with Forms ๐
Handling Form Data โ $_GET and $_POST. ๐ฅ
Validation & Sanitization โ filter_var(), htmlspecialchars(). ๐ก๏ธ
File Uploads โ Handling $_FILES array. ๐
4๏ธโฃ Working with Databases (MySQL & PDO) ๐๏ธ
Connecting to a Database โ mysqli_connect() or PDO. ๐
Executing Queries โ SELECT, INSERT, UPDATE, DELETE. ๐โ๏ธ
Prepared Statements โ Prevent SQL injection using prepare(). ๐
5๏ธโฃ PHP and Sessions ๐ช
Sessions โ Store user data across pages (session_start();). ๐
Cookies โ Store small pieces of data on the client (setcookie();). ๐ช
6๏ธโฃ Object-Oriented Programming (OOP) in PHP ๐๏ธ
Classes & Objects โ Define with class and instantiate using new. ๐งฑ
Encapsulation โ Use public, private, protected. ๐ฆ
Inheritance โ Extend functionality using extends. ๐ณ
Polymorphism & Interfaces โ Create flexible code structures. ๐งฌ
7๏ธโฃ File Handling ๐
Reading & Writing Files โ fopen(), fread(), fwrite(). ๐โ๏ธ
Working with JSON & XML โ json_encode(), json_decode(). ๐
8๏ธโฃ REST APIs with PHP ๐
Handling API Requests โ $_GET, $_POST. ๐ก
JSON Response โ header("Content-Type: application/json");. ๐ค
cURL for API Calls โ curl_init(), curl_exec(). ๐
9๏ธโฃ Security Best Practices ๐ก๏ธ
Prevent SQL Injection โ Use prepared statements. ๐ซ๐ซ
Cross-Site Scripting (XSS) Prevention โ htmlspecialchars(). ๐งผ
Cross-Site Request Forgery (CSRF) Protection โ Use tokens. ๐ซ
Password Hashing โ Use password_hash(), password_verify(). ๐
๐ PHP Frameworks & Tools ๐งฐ
Laravel โ Modern PHP framework for web applications. ๐ฆ
CodeIgniter โ Lightweight MVC framework. ๐
Composer โ Dependency manager for PHP. ๐ฆ
