FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

基于webman加mysql实现的可视化简易版消息队列

介绍

基于webman + mysql 实现的简易消息队列.
前面使用reids消息队列部署到服务器上的时候,第一次启动的时候,由于自己配置没配好,导致启动出现异常 然后把配置改好了,再次启动后却发现某一个消息队列无法执行了,调试打印添加啥的乱搞一通都没有任何反应,后面实在找不出问题出在哪了,想着要不换个名称试试看,结果换了名称直接就正常了.
正是基于这个背景下,我觉得它可能不是我想要的消息队列,于是开发了这个简易版的可视化消息队列组件,

如果你想使用该组件的话,请仔细阅读并理解清楚它的特性再决定

1 从程序的逻辑上来说,基本可以保证数据不会丢失
2 服务端无法支持分布式跟多进程，消费端分布式的话必须保证时间与服务端保持一致，不然会导致消息无法推送
3 同一个队列只能说基本能按顺序执行，反过来听就是不保证他能按顺序执行,例如后发先至、推送失败重试等等是没法保证消息按入队顺序执行的
4 不保证只推送一次,重要数据消费里必须做好幂等性.
5 不管你开多少个消费者,同一类型队列,同一次推送只会有一条消息推送执行
6 性能的话,取决于你服务器情况,我在自己这实测的话,2核的轻量服务器,写入1000条左右耗时1.2秒左右,加上同时进行消费,服务器占用率已经达到60%了,所以仅建议小项目用，有高并发的话，请使用专业的消息队列。
