Why upgrade thinkphp3 to thinkphp5

Among the many PHP frameworks, ThinkPHP has always been one of the preferred frameworks for the majority of PHP developers. The ThinkPHP framework is also constantly being updated and upgraded. Recently, the more advanced ThinkPHP5 version was launched, which has been welcomed by many developers. So, why should we upgrade ThinkPHP3 to ThinkPHP5? This article will explore this issue from multiple perspectives.

1. New functions and advantages

Compared with ThinkPHP3, ThinkPHP5 has significant improvements in new functions and performance advantages. The most obvious one is that the core of the framework adopts a more advanced namespace management mechanism, which can greatly improve the readability and maintainability of the code. In terms of performance advantages, ThinkPHP5 supports more efficient file caching and static caching, which greatly improves the system's response speed. In addition, ThinkPHP5 also introduces modular development based on Composer, which supports more flexible module definition and module calling, which can well meet the needs of large projects.

2. Blog system case

Let’s take the blog system as an example to compare the performance improvements brought by the upgrade of ThinkPHP3 and ThinkPHP5. Take my blog system as an example. The system adopts the MVC design pattern, and the data access object (DAO) interacts with the database. It also uses the Smarty template engine to render the front-end page. The test results are as follows:

1. The first is the loading page speed test. We used the ApacheBench tool for this test, with 5,000 requests and a thinking time of 500ms. The test results are:

The average response time of ThinkPHP3 is 135ms, the slowest response time is 422ms, and the throughput is 370.37 req/sec;
The average response time of ThinkPHP5 is 92ms, and the slowest response time is 798ms, throughput is 543.48 req/sec.

The test results show that the performance of ThinkPHP5 is significantly better than ThinkPHP3.

2. The next test is the request time of the article list page. This test also uses the ApacheBench tool and requests 1,000 times. The test results are:

ThinkPHP3 average request time is 253ms, the longest time is 855ms;
ThinkPHP5 average request time is 145ms, the longest time The time is 329ms.

It is also an obvious performance advantage.

3. Framework update and upgrade

Framework update and upgrade is another important reason for the launch of the new version. ThinkPHP5 has greater improvements in scalability and components than ThinkPHP3. This version supports two application-level configuration files (common.php and config.php), strips out more core libraries to expand the component nature of the framework, and is in line with the emerging componentization trend in the PHP world. The new version of the framework has also made more optimizations in API design. In addition to better readability and maintainability, it also maintains compatibility with the old version while improving efficiency and stability in development and deployment.

4. Developer and community support

We know that for an open source framework, having an active community and developers is crucial. Over time, ThinkPHP has been continuously updated and upgraded in many aspects, and has also received support from more and more developers and communities. For example, the ThinkPHP community is better in terms of richness of third-party components, complete TDD tool chain and stability, etc., and can often help you deal with problems in some extreme situations.

In general, upgrading to ThinkPHP5 has many advantages and benefits for developers. In addition to higher performance, more advanced feature and framework updates and upgrades, and better developer and community support. If you are using an older version of ThinkPHP, you may consider upgrading to ThinkPHP5 and experience a better programming experience.
