How to convert from PHP to Next

Introduction to Converting PHP to Next

Converting a PHP application to Next.js (a React-based framework for production environments) can be a strategic step to enhance performance, scalability, and maintainability. This guide will provide a structured approach to transition your PHP codebase to Next.js, ensuring you leverage the benefits of modern JavaScript frameworks.

Preparation and Setup

Before diving into the conversion process, ensure you have the following set up:

  • Node.js and npm installed on your machine.
  • A clear understanding of your existing PHP codebase.
  • Basic familiarity with JavaScript and React.

Understanding the Differences

PHP and Next.js have fundamental differences in architecture and execution:

  • PHP: Server-side scripting language primarily used for backend development.
  • Next.js: React framework used for server-side rendering and static site generation. It handles both frontend and backend logic.

Creating the Next.js Environment

  1. Initialize a New Next.js Project:

    Use the following command to create a new Next.js application:

    npx create-next-app@latest
    cd my-next-app
  2. Directory Structure:

    • Replace PHP directories (public, includes, etc.) with Next.js structure (pages, public, components).

Converting PHP Templates to React Components

  1. Identify PHP Templates:

    • Locate your .php files responsible for rendering HTML. These are typically used for views. Example: index.php, header.php, footer.php.
  2. Create Corresponding React Components:

    • Convert each PHP template into a React component. Example:
      <!-- PHP Code (header.php) -->
        <h1><?php echo $title; ?></h1>
      Convert to React:
      // React Component (Header.js)
      const Header = ({ title }) => (
      export default Header;

Replacing Server-Side Logic

  1. Transform PHP Backend Logic to Next.js API Routes:

    • PHP performs a lot of business logic on the server side. In Next.js, you can create API routes to handle server-side logic. Example:
      // PHP Code (data.php)
      $data = fetchDataFromDatabase();
      echo json_encode($data);
      Convert to Next.js API Route:
      // Next.js API Route (pages/api/data.js)
      import { fetchDataFromDatabase } from '../../lib/db';
      export default async function handler(req, res) {
        const data = await fetchDataFromDatabase();
  2. Database Connections:

    • Example in PHP:
      // PHP Code (db.php)
      $conn = new mysqli($servername, $username, $password, $dbname);
      Convert to Next.js using a library like pg or mongoose:
      // Next.js (lib/db.js)
      import { Client } from 'pg';
      const client = new Client({ connectionString: process.env.DATABASE_URL });
      await client.connect();

Handling Forms and User Input

  1. PHP Example:
    <!-- PHP Code (form.php) -->
    <form action="submit.php" method="POST">
      <input type="text" name="username" />
      <button type="submit">Submit</button>
  2. React Conversion:
    // React Component (Form.js)
    import { useState } from 'react';
    const Form = () => {
      const [username, setUsername] = useState('');
      const handleSubmit = async (e) => {
        const response = await fetch('/api/submit', {
          method: 'POST',
          headers: {
            'Content-Type': 'application/json',
          body: JSON.stringify({ username }),
      return (
        <form onSubmit={handleSubmit}>
            onChange={(e) => setUsername(}
          <button type="submit">Submit</button>
    export default Form;


Converting a PHP application to Next.js involves a systematic approach to replicate PHP functionalities using modern JavaScript and React paradigms. By following this guide, you can migrate from PHP to a more robust, performant, and scalable Next.js application, leveraging its powerful features for both server-side rendering and static site generation. Remember, understanding both PHP and Next.js concepts is crucial to ensure a smooth transition and maintain your application's integrity.
