Question

对于耗时的任务（电子邮件发送，图像处理......你明白了），我想运行异步PHP任务。

它是quite easy on Linux，但我正在寻找一种适用于Windows的方法。

我希望它变得简单，应该如此。没有artillery，没有SQL排队，没有一次又一次installing stuff ...我只想运行一个该死的异步任务。

所以我尝试了Symfony Process Component。问题是，同步运行任务工作正常，但在异步运行时，它会沿主脚本退出。

有没有办法解决这个问题？

composer require symfony/process

的index.php

<?php
require './bootstrap.php';
$logFile = './log.txt';

file_put_contents($logFile, '');

append($logFile, 'script (A) : '.timestamp());

$process = new Process('php subscript.php');
$process->start(); // async, subscript exits prematurely…
//$process->run(); // sync, works fine

append($logFile, 'script (B) : '.timestamp());

subscript.php

<?php
require './bootstrap.php';
$logFile = './log.txt';

//ignore_user_abort(true); // doesn't solve issue…

append($logFile, 'subscript (A) : '.timestamp());
sleep(2);
append($logFile, 'subscript (B) : '.timestamp());

bootstrap.php中

<?php
require './vendor/autoload.php';
class_alias('Symfony\Component\Process\Process', 'Process');

function append($file, $content) {
    file_put_contents($file, $content."\n", FILE_APPEND);
}

function timestamp() {
    list($usec, $sec) = explode(' ', microtime());
    return date('H:i:s', $sec) . ' ' . sprintf('%03d', floor($usec * 1000));
}

结果

script (A) : 02:36:10 491
script (B) : 02:36:10 511
subscript (A) : 02:36:10 581
// subscript (B) is missing

Answer 1

异步处理完成后，主脚本必须等待。试试这段代码：

$process = new Process('php subscript.php');
$process->start();
do {
    $process->checkTimeout();
} while ($process->isRunning() && (sleep(1) !== false));
if (!$process->isSuccessful()) {
   throw new \Exception($process->getErrorOutput());
}

Answer 2

不是最好的解决方案，但是：

$process = new Process('nohup php subscript.php &');
$process->start();

Answer 3

如果php supports fpm for Windows，您可以收听 { "id": "tblCustomer", "name": "tblCustomer", "columns": [ { "id" : "thCustIndex", "name" : "thCustIndex", "title" : "Sr. #", "classes" : "", "type" : "index", "sortable" : "true", "editable" : "false" }, { "id" : "thCustId", "name" : "thCustId", "title" : "Id", "classes" : "align-center", "type" : "text", "sortable" : "true", "editable" : "false" }, { "id" : "thCustName", "name" : "thCustName", "title" : "Name", "classes" : "", "type" : "text", "sortable" : "true", "editable" : "false" }, { "id" : "thCustDob", "name" : "thCustDob", "title" : "Date Of Birth", "classes" : "", "type" : "date", "sortable" : "true", "editable" : "false" }, { "id" : "thCustMobile1", "name" : "thCustMobile1", "title" : "Mobile 1", "classes" : "", "type" : "inMobile", "sortable" : "true", "editable" : "false" }, { "id" : "thCustEmail", "name" : "thCustEmail", "title" : "E-mail Id", "classes" : "align-center", "type" : "email", "sortable" : "true", "editable" : "false" }, { "id" : "thCustAddress", "name" : "thCustAddress", "title" : "Address", "classes" : "", "type" : "text", "sortable" : "true", "editable" : "false" } ]事件，以便在发送回复后提供所有昂贵的任务。

服务：

kernel.terminate

监听器：

app.some_listener:
    class: SomeBundle\EventListener\SomeListener
    tags:
        - { name: kernel.event_listener, event: kernel.terminate, method: onKernelTerminate }

使用Symfony Process运行异步PHP任务
