This article mainly introduces the PHP multithreaded programming pipeline communication example analysis, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor with you to understand.

The specific analysis is as follows:

If a thread is individual heroism, then multi-thread is collectivism, you are no longer a loner, but a conductor.

Pipeline communication:

1. A pipeline can be thought of as a queue to which different threads can write or read. Just write.

Add at the end of the queue and read is deleted at the head of the queue.

two。 The pipe generally has a size, and the default is 4K, that is, if the content is more than 4K, you can only read it and cannot write in it.

3. By default, after the pipe is written, it is blocked until the program that reads it has read the data. And the reading thread will be blocked.

Until a process writes data to the pipe. Of course, you can change this default property and use the stream_set_block function to set it to non-blocking mode.

The following is a pipeline class that I sub-packaged (there is a problem with the naming of this class, there is no uniform, and there is no time to change it to uniform. I usually write the test code first and then subpackage it, so the naming may not be uniform):

/ * with this class, you can implement simple pipeline communication. * / Thank you for reading this article carefully. I hope the article "sample Analysis of Pipeline Communication in PHP Multithreaded programming" shared by the editor will be helpful to you. At the same time, I also hope that you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
