Some useful system utils for php

• exec system command
• simple process usage
• php env info
• error and exception info

Install

composer require toolkit/sys-utils

Usage

ProcTasks

Example:

use Toolkit\Sys\Proc\ProcTasks;

// ProcTasks::new() // will auto get cpu num as proc num
ProcTasks::new(['procNum' => 2])
 ->setTaskHandler(function (array $task, array $ctx) {
 $pid = $ctx['pid'];
 println("worker#{$ctx['id']} [PID:$pid] - handle task, task data", $task);
 sleep(random_int(1, 3));
 })
 ->onBeforeCreate(fn($pid, $num) => println("master [PID:$pid] - Will create task process, number:", $num))
 ->onWorkersCreated(fn($pid, $info) => println("master [PID:$pid] - All task process started,", 'Workers info', $info))
 ->onWorkerStart(fn($pid, $id) => println("worker#$id started, pid is", $pid))
 ->onWorkerExit(fn($pid, $id) => println("worker#$id exited, pid is", $pid))
 ->onCompleted(fn($pid) => println("master [PID:$pid] - all workers exited, tasks run completed"))
 ->setTasks([
 ['task1'], // one task
 ['task2'],
 ['task3'],
 ['task4'],
 ])
 ->addTask(['task5'])
 ->run();

Run:

php example/proc-tasks.php

Output:
