To sum up
What has changed in OpenCart 4?
What has changed between the most recent major version and the earlier OpenCart platform build: OpenCart 4 vs OpenCart 3?
●Ocmod cannot be used. Currently, Events must be used to integrate the modules.
●The structure of the folders used to store modules: Each extension (or author) will have its own directory inside the new root directory /extension/, which now houses all add-on files. The intermediate extension folder was also deleted at the same time. As a result, the following will be the path to the module's front-end controller: /extension/opencartbot/catalog/controller/module/new module.php. Additionally, the following will be the path to the module template: /extension/opencartbot/catalog/view/template/module/new module.twig
●The product block that was previously in the list templates has been moved to product/thumb.twig. To modify the button or add stickers to the product, you no longer need to edit all of the templates.
●The common/pagination.twig template now contains pagination.
●Ability to produce multiple versions of a single product
●Tools for GDPR regulation compliance
●a single-page checkout form
●The CRON Task Scheduler
●Possibility to rename the admin
●Version 8.1+ of PHP is the bare minimum utilized.
●The layout has changed since the Bootstrap framework, which is being used, has been updated to version 5.
●Version 5 of the font collection Font Awesome
●Added jQuery 3.6.0, a new version of the library
●After installing the new edition, you can see a lot more modifications and enhancements.
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.
Website Loading Speed
Opencart comparison
Website loading speed
The loading speed of OpenCart 4 vs OpenCart 3 can be compared by the following metrics: page size, number of requests, and time to the first byte. OpenCart 3 has a larger page size, but fewer requests. The time to the first byte is slower for OpenCart 3. OpenCart 4 has a smaller page size and more requests. The time to the first byte is faster for OpenCart 4.
In general, OpenCart 4 is faster than OpenCart 3 when it comes to loading pages and processing requests. This can be attributed to the fact that OpenCart 4 uses a new framework that is designed for improved performance. As a result, customers are more likely to have a positive experience on an OpenCart 4 site, which can lead to increased sales and conversions.
The most stable OpenCart version
According to the user community, the most stable version of OpenCart is OpenCart 3.0.3.8 (the final version of OpenCart 3). This release includes several improvements and bug fixes, such as improved support for MySQL 8, improved security when using VQMod, and increased stability when using the payment and shipping methods.
This version is known to be the most stable one so far, with many new features and improvements that make it even easier to use. One of the biggest new features is the built-in support for multiple languages. This means that you can now reach a wider audience with your online store.
In addition, OpenCart 3.0.3.8 also includes improved support for mobile devices, as well as various security enhancements. If you are running an online business, then you should definitely use this version of OpenCart.
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 4.0.0.0 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. And with the help of a reliable OpenCart migration tool, you can make this switch much more easily!

注解：
The statement the author provided outlines several changes between OpenCart 3 and OpenCart 4, and it is mostly accurate based on current available information. Here's a breakdown of the key points:
- OCMOD not supported: Correct. OpenCart 4 has moved away from OCMOD, relying on an event-driven architecture instead for module integration, meaning developers must adapt their modules to use Events rather than OCMOD.
- Folder structure for extensions: This is also correct. In OpenCart 4, each extension now has its own directory under the new /extension/ folder, eliminating the intermediate "extension" folder. This change is aimed at improving module organization and modular development.
- Product block in list templates: The shift of the product block to product/thumb.twig is accurate. This change simplifies how developers handle front-end modifications, such as buttons or stickers for products.
- Pagination in common/pagination.twig: Correct. Pagination logic has been consolidated into this template.
- Multiple versions of a single product: This feature has been introduced, allowing store owners to create product variants, which was not available in OpenCart 3 by default.
- GDPR compliance tools: These tools have been added in OpenCart 4 to assist with handling customer data in compliance with privacy regulations.
- Single-page checkout: This improvement enhances the checkout experience by consolidating the process into one page.
- CRON task scheduler: The introduction of a CRON scheduler is another new feature in OpenCart 4.
- Renaming admin folder: OpenCart 4 allows renaming the admin directory for security purposes, as a measure to prevent unauthorized access.
- PHP 8.1+ requirement: Correct. OpenCart 4 requires a minimum of PHP 8.1 for its operation.
- Bootstrap 5 and Font Awesome 5: The platform has updated its front-end framework to Bootstrap 5 and upgraded its icons to Font Awesome 5.
- jQuery 3.6.0: The latest version of the jQuery library is used in OpenCart 4.
In summary, the changes mentioned between OpenCart 3 and OpenCart 4 are factual and reflect the significant updates made in the platform's architecture, module management, and usability.
作者提供的描述关于 OpenCart 3 和 OpenCart 4 之间的变化基本上是准确的，以下是每个要点的中文解释：
- 不支持 OCMOD：这是正确的。在 OpenCart 4 中，OCMOD 不再被支持，转而采用基于事件的架构。这意味着开发者必须适应使用事件系统来集成模块，而不是依赖 OCMOD。
- 扩展的文件夹结构：这个描述也是正确的。在 OpenCart 4 中，每个扩展都在新的 /extension/ 目录下拥有自己的文件夹，这种变动优化了模块的管理，并使模块化开发更有条理。
- 产品块在列表模板中的调整：产品块移动到 product/thumb.twig 的描述是正确的。这简化了开发者对前端的修改，如产品按钮或贴纸的更改。
- 分页模板的调整：正确。分页逻辑现在集中在 common/pagination.twig 模板中。
- 单个产品的多个版本：这个功能在 OpenCart 4 中确实被引入，允许店主创建产品的不同版本（如不同颜色或尺寸），这是 OpenCart 3 中默认缺乏的功能。
- GDPR 合规工具：OpenCart 4 添加了 GDPR 合规工具，帮助管理客户数据以符合隐私法规。
- 单页结账：这个改进将结账过程简化为一个页面，提升了用户体验。
- CRON 任务调度器：OpenCart 4 新增了 CRON 任务调度器这一功能。
- 重命名管理员文件夹：OpenCart 4 允许重命名管理员目录，以增加安全性，防止未经授权的访问。
- PHP 8.1+ 要求：这是正确的。OpenCart 4 需要至少 PHP 8.1 版本才能运行。
- Bootstrap 5 和 Font Awesome 5：平台已经更新了前端框架，使用 Bootstrap 5 和升级后的 Font Awesome 5 图标。
- jQuery 3.6.0：OpenCart 4 使用了 jQuery 库的最新版本 3.6.0。
总的来说，提到的这些变化准确地反映了 OpenCart 4 在架构、模块管理和用户体验方面的重大更新。
