This article mainly introduces how to use multi-process programming functions in PHP using examples, including processing zombie processes! You can refer to a set of process control functions in PHP (enable-pcntl and posix extensions are required during compilation ), php allows you to create sub-processes, execute programs using exec functions, and

)Popen2. Popen3 and Popen2. Popen4 basically work as subprocess. Popen, except that:Popen raises an exception if the execution fails.The Capturestderr argument is replaced with the stderr argument.Stdin=pipe and Stdout=pipe must be specified.Popen2 closes all file descriptors by default, and you have to specify Close_fds=true with Popen.1.5. NOTES1.5.1. Converting an argument sequence-a string on WindowsOn Windows, an args sequence are converted to a string that can be parsed using the following

frequently, you cannot use communicate ();Because the communicate communication closes the pipeline once. You can try the following method:P= subprocess. Popen (["WC"], stdin=subprocess. Pipe,stdout=subprocess. Pipe,shell=true)P.stdin.write (' Your command ')P.stdin.flush ()#......do somethingTry#......do somethingP.stdout.readline ()#......do somethingExceptPrint (' IOError ')#......do something MoreP.stdin.write (' Your other command ')P.stdin.flush ()#......do something More2.2 subprocess ch

Examples of PHP multi-process pcntl_fork and pcntl_fork Example of pcntl_fork for PHP multi-process editing In fact, PHP supports concurrency, but it is rarely used at ordinary times. Usually the most used should be to use the PHP-FMP to schedule the php process. However, the use of PHP is not limited to Web. We can al

The examples in this article describe Python multiprogramming (multiprocessing) usage. Share to everyone for your reference. The specific analysis is as follows: Because of the limitations of Python design (I'm talking about our usual cpython). Up to 1 CPU cores can be used. Python provides a very useful multiprocessing package, and you just need to define a function that Python will do everything else for you. With this package, you can easily comp

If the command is passed, it is generally called JPS to view the specific PID, then call Jstat to see the runtime memory, and the frequency of the GC, and then through Jstack to see if the thread is blocking, deadlock, looping, and so on, finally through Jmap generated heap snapshot to analyze memory overflow.With Visual Tools:In the case of jconsole, you can view the heap and the memory of each part through the memory window, and through the thread window you can see if the thread waits, loops,
