July 2019

Today, Alibaba Cloud officially launched a full image of PHP Composer. All PHP developers can accelerate the Composer installer through our developer community, developer.aliyun.com/composer.

The biggest advantage of this image tool is that it is fast, almost achieving real-time synchronization with the PHP Packagist official, and refreshing the national CDN cache every 30 seconds. It develops a synchronization system based on AliCloud's object storage OSS and CDN, and achieves fast and stable synchronization through task distribution.

Why develop this image tool?

This actually comes from the common demands of customers and Alibaba Group business.

There are tens of thousands of PHP SDK users on Alibaba Cloud. To improve the installation success rate, the fastest image synchronization tool must be available.

In addition, nearly 60000 enterprise developers are active in our one-stop enterprise collaborative R&D cloud cloud efficiency platform, and build PHP projects through the cloud efficiency platform, which is also inseparable from the image synchronization tool.

Why open the download of this tool?

Because we are also beneficiaries of the PHP community, we hope to give back. We also hope to polish better tools under the supervision of PHPer.

In the past week, we conducted a small scale developer beta.

I am very happy that without any official promotion, this tool has been downloaded more than 300000 times a day, and many developers even spontaneously promote it. At the same time of surprise and gratitude, we also found many problems and constantly improved and adjusted them.

Today, we can officially announce the launch of Alibaba Cloud Composer full image, and we are confident that we are capable of serving a wider range of PHPer.

Here we also pay tribute to Larry China developer Summer and Zen Master:

There is no doubt that we are also the beneficiaries of Larravel China. Thank you for your contribution to the PHP community, and also thank Summer for our recognition. Alibaba Cloud will continue to work hard to make the PHP community better together!
