How to Build a Simple PHP CRUD Application

Ready to build a simple task manager using PHP and MySQL? In this video, we’ll walk you through creating a CRUD (Create, Read, Update, Delete) application step-by-step. You’ll learn how to set up your database, organize your project files, and implement each CRUD operation. By the end, you’ll have a functional task manager that allows users to interact with a database. Let’s dive into this practical tutorial!

Learn:

What is a CRUD Application?
📋 A CRUD application allows users to interact with a database by performing four key operations:
✅ Create: Add new records.
✅ Read: View existing records.
✅ Update: Modify existing records.
✅ Delete: Remove records.

💡 In this tutorial, we’ll build a simple task manager using PHP and MySQL.

Prerequisites:

Before starting, ensure you have the following installed:
PHP: For server-side scripting.
MySQL: For storing task data.
Apache or Nginx: To serve the PHP files.

💡 You can use XAMPP or LAMP stack for an all-in-one setup.

Step 1: Create the Database
📚 First, create a database and table to store tasks:
Open your MySQL terminal or phpMyAdmin.

Run these commands to create a database and table:

CREATE DATABASE task_manager;
USE task_manager;

CREATE TABLE tasks (
id INT AUTO_INCREMENT PRIMARY KEY,
title VARCHAR(255) NOT NULL,
description TEXT,
status ENUM('pending', 'completed') DEFAULT 'pending'
);

💡 This creates a tasks table with columns for task details and status.

Step 2: Set Up the Project Structure
📂 Organize your project files as follows:
Copy
/task-manager/
├── index.php // List all tasks
├── add.php // Add a new task
├── edit.php // Edit an existing task
├── delete.php // Delete a task
└── db.php // Database connection

Step 3: Create the Database Connection
🔗 Save the following code as db.php:

(db.php) you can download script file from the gitlab link bellow

💡 This script connects to the MySQL database and ensures all other scripts can reuse the connection.

Step 4: Display Tasks (index.php)
📋 Create a page to display all tasks:

(index.php) you can download script file from the gitlab link bellow

💡 This script fetches tasks from the database and displays them in a table.

Step 5: Add a New Task (add.php)
📝 Create a form to add new tasks:

(add.php) you can download script file from the gitlab link bellow

💡 This script inserts a new task into the database and redirects back to the task list.

Step 6: Edit a Task (edit.php)
✏️ Allow users to update existing tasks:

(edit.php) you can download script file from the gitlab link bellow

💡 This script updates a task based on its ID and redirects back to the task list.

Step 7: Delete a Task (delete.php)
✂️ Allow users to delete tasks:

(delete.php) you can download script file from the gitlab link bellow

💡 This script deletes a task based on its ID and redirects back to the task list.

Summary:

Create Add new tasks add.php
Read View all tasks index.php
Update Edit existing tasks edit.php
Delete Remove tasks delete.php
