There are several considerable advantages to using Opencart 4. Typically, the interface is more user-friendly, and it’s easier to find the features you need. In addition, Opencart 4 is more efficient and faster than its predecessor.

While OpenCart 4.0 is still relatively new, it has already made a big impact in eCommerce stores. In terms of features, OpenCart 4.0 boasts a number of significant improvements over its predecessor, OpenCart 3.0.

Compatible PHP Version

OpenCart 3 is designed to work with PHP 7.1 or later, while Opencart 4 is compatible with PHP 8.1 or later. Earlier versions of Opencart (3.x) are not compatible with PHP 8.1, and therefore cannot be upgraded to Opencart 4.

If you are running an older version of PHP on your server, you will need to upgrade to a newer version in order to install Opencart 4. Once you have upgraded your PHP version, you will then be able to install Opencart 4 and take advantage of its new features and improvements.

Code Structure

OpenCart 4 vs OpenCart 3 both use a modular structure for code, which means that each functionality is kept in its own module. This makes it easy to customize the functionality of the platform to suit your specific needs. In addition, the modular code structure ensures that upgrades are quick and easy to implement, as only the relevant modules need to be updated.

OpenCart 4 introduces a new directory structure, which is designed to be more consistent and easier to understand. In addition, OpenCart 4 uses namespaces for code, which helps to avoid name clashes between different modules. As a result, the overall code structure of OpenCart 4 is more robust and easier to work with than that of OpenCart 3. Also, Opencart 4 offers a flexible and scalable solution for any eCommerce business.

The code structure of OpenCart 3 is based on the MVC (Model-View-Controller) framework. MVC is a software architecture pattern that divides a program into three parts: the model, the view, and the controller. The model represents the data, the view displays the data, and the controller handles the user input.

Database structure of OpenCart 4 vs OpenCart 3

OpenCart 3

Opencart 3 uses a MySQL database. The main benefit of using a MySQL database is that it can be easily accessed and updated using a variety of tools. Opencart 3 also supports the use of other databases, such as PostgreSQL, but MySQL is the recommended database for most users.

The structure of the Opencart 3 database is modular, making it easy to add new features and functionality. The core tables in the database function to store product data, customer data, order data, and other essential information. In addition, there are several third-party plugins that add additional tables to the database.

These plugins can add support for custom fields, payment methods, shipping methods, and much more. As a result, the Opencart 3 database is highly flexible and can be easily customized to meet the needs of any online store.

OpenCart 4

The OpenCart 4 vs OpenCart 3 database structure is similar, but there are some important differences to be aware of. The biggest difference is that OpenCart 4 uses a NoSQL database, which means that it does not use the traditional relational model. This makes it more flexible and scalable, but it also means that there are some trade-offs in terms of performance and ease of use.

Another difference is that OpenCart 4 uses a schema-less database, which means that data can be stored in any format. This makes it easy to store and query data, but it also means that there is no strict structure to follow.

Finally, OpenCart 4 uses a document-oriented database, which means that data is stored in documents instead of tables. This makes it more scalable and flexible, but it also means that there is no strict structure to follow.

OpenCart 4 vs OpenCart 3: Which one is better?

If you’re new to Opencart, you might be wondering which version is right for you. While both Opencart 4 vs Opencart 3 have their pros and cons, we think that, for new users, Opencart 3 is a better choice. Here’s why:

  • First of all, Opencart 4 is still relatively new – the very first version was only released 1 month ago. Because it’s so new, there are bound to be more bugs than in the older, more established Opencart 3.
  • In addition, support for Opencart 4 is still somewhat limited – there aren’t as many extensions and themes available yet, and the community isn’t as large.
  • One key difference is in the number of modules available. OpenCart 4 has been out for less than a month, and there are only three sub-versions available. This means that the number of modules that support OpenCart 4 is smaller and more limited.

To sum up

OpenCart eCommerce platform has been around for over a decade. Over the years, it has undergone several major updates, with the most recent being the release of OpenCart 4.0. This was recently confirmed by the development team, who have been working hard on developing and testing the new version.

If you are currently running OpenCart 3, please be aware that there may be some bumps in the road ahead as you make the switch to OpenCart 4. And there are a lot of considerations between OpenCart 4 vs OpenCart 3. However, we believe this new version is well worth it for its improved stability and features.
