When PHP is running, kill it directly, which may lead to data loss. Fortunately, the PHP module handles signal. First, check whether the pcntl module is installed. Then, you can add the followingCode Global $ exitflag; $ Exitflag = false; // Add Linux semaphore ProcessingIf (directory_separator! = '//'){Pcntl_signal (sigterm, "sig_handler ");Pcntl_signal (sighup, "sig_handler ");Pcntl_signal (SIGINT, "sig_handler ");} // Signal Processing FunctionFunction sig_handler ($ si

frequency combination of PX and py is very likely to represent the recognition of a DTMF symbol. However, we also need to make a series of judgments to further evaluate: are px and py strong enough? We can set a threshold, if both PX and PY are below this threshold, then n samples are evaluated to not recognize the DTMF symbol. Reference [2] suggests that the threshold value is 400000. is the difference between PX and py too large? The normal DTMF signal, the two energies should be

ObjectiveNot in-depth research process and signal, just I a rough understanding.What is a process?1. When the program is not run by the parser, it is just a static file or data stream.2. When the program is run by the parser, a process is generated that represents a state of the current program runtime.Parent-child processes1. The process is like real-life people, also have a father-son relationship.2. The child process inherits the parent process, but the child process is independent.3. If the
