What are the reasons for upgrading thinkphp3 to thinkphp5?

1. New functions and advantages

ThinkPHP5 has greatly improved in terms of new functions and performance, and has obvious advantages over ThinkPHP3. The most significant feature is that the core of the framework adopts a more advanced namespace management mechanism, which can effectively improve the readability and maintainability of the code. ThinkPHP5 has more efficient file caching and static caching functions, which has obvious advantages in performance, which can greatly improve system 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

The following takes the blog system as an example to compare the performance improvements of ThinkPHP3 and ThinkPHP5 upgrades. 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 use the ApacheBench tool for testing, making 5000 requests and thinking time of 500ms. The test results are:

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

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

It is also an obvious performance advantage.

3. Framework updates and upgrades

Framework updates and upgrades are another important reason for the launch of the new version. ThinkPHP5 has greater improvements, including but not limited to scalability and components, compared to 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

Having an active community and developers is crucial for an open source framework, this is what we know of. 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.

What is thinkphp

thinkphp is a free development framework that can be used to develop front-end web pages. The earliest thinkphp was created to simplify development. Thinkphp also follows the Apache2 protocol. It was originally Evolved from Struts, we also make use of some good foreign framework patterns, use object-oriented development structures, and are compatible with many tag libraries and other patterns. It can develop and deploy applications more conveniently and quickly, and of course it is not just enterprise-level applications. , any PHP application development can benefit from the simplicity, compatibility and speed of thinkphp.
