The library help to work with processes. It provides a more readable api and various modes for IPC via pipe(FIFO) and system v.
Install via composer
composer require slince/processThe library replies on the following php's extension.
- ext-pcntl. Provides control processes (MUST)
- ext-sysvshm. Porvides system v shared memory (OPTIONAL)
- ext-sysvsem. Porvides system v semaphore (OPTIONAL)
- ext-sysmsg. Porvides system v message queue (OPTIONAL)
$process = new Slince\Process\Process(function(){ echo 'hello, my pid is ' . getmypid(); }); $process->start(); var_dump($process->isRunning()); // echo true var_dump($process->getPid()); // will output the pid of child process //do something other $process->wait(); //waiting for the process to exit Note: If your php version is less than 7.1, please add the statement
declare(ticks=1);at the beginning of the file:
$process = new Slince\Process\Process(function(){ Slince\Process\Process::current()->signal([SIGUSR1, SIGUSR2], function(){ echo 'trigger signal'; }); echo 'hello, my pid is ' . getmypid(); }); $process->start(); $process->signal(SIGUSER1); //do something $process->wait();$memory = new Slince\Process\SystemV\SharedMemory(); $memory->set('foo', 'bar'); var_dump($memory->get('foo'));The default size of shared memory is the sysvshm.init_mem in the php.ini, otherwise 10000 bytes. You can adjust this.
