The provided document outlines several PHP practical programs, ranging from basic calculations to database management.
### **Basic PHP Operations**
* **Sum of Two Numbers**: A program that adds two variables, `$a` and `$b`, using the syntax `$sum = $a + $b` and displays the result.
* **Even and Odd Check**: Uses the modulus operator (`%`) to determine if a number is even (remainder is 0) or odd.
* **Prime Numbers**: A nested loop program that identifies and prints prime numbers between 1 and 100.
* **String Manipulation**:
* **Compare Two Strings**: Uses `strcmp()` to determine if strings are equal or their alphabetical order, and the `==` operator for equality checks.
* **Reverse a String**: Demonstrates reversing a string using the built-in `strrev()` function and a manual `for` loop.
### **Functions and Arrays**
* **Recursion**: A recursive function is used to print numbers from 1 to N, alongside a bonus example for calculating factorials.
* **Associative Arrays**: Demonstrates creating an array with key-value pairs and iterating through it using a `foreach` loop.
### **Advanced Concepts and Web Integration**
* **Form Design**: An HTML form that collects user data (name, email, age) and processes it with PHP using the `$_POST` superglobal and `htmlspecialchars()` for security.
* **Object-Oriented Programming (OOP)**: Covers key concepts including classes, objects, constructors (`_construct()`), properties, methods, and inheritance.
### **Database Management (MySQLi)**
* **Database and Table Creation**: Steps to connect to a MySQL server, create a database named `StudentDB`, and establish a `students` table.
* **CRUD Operations**: Demonstrates how to **I**nsert, **S**elect, **U**pdate, and **D**elete records within a database.
* **Database Guide**: Provides both PHP code methods and phpMyAdmin (GUI) steps for creating, editing (adding/renaming/modifying columns), and deleting databases and tables.
