Php 为什么我们需要使用proc_open for workers？

下面是

PHP worker

示例的代码。网络上的所有示例都使用proc_open（）并打开子进程来执行作业

带有子进程的Worker.php

---

但使用php寄存器错误处理程序，我们可以捕获php工作者错误，然后将失败的作业写入数据库

我的问题是，如果我们使用supervisord，为什么我们需要打开子进程

没有子进程的Worker.php 使用主管

vi myMailer.conf

[program:myMailer]
process_name=%(program_name)s_%(process_num)02d
command=php /var/www/project/worker.php --memory:128 --delay=0 --timeout=3
numprocs=3
autostart=true
autorestart=true
stdout_logfile=/var/www/project/data/logs/myMailerProcess.log
stdout_logfile_maxbytes=1MB

启动所有工人

supervisorctl start all

myMailer_02: started
myMailer_01: started
myMailer_00: started

myImages_02: started
myImages_01: started
myImages_00: started

然后开始这个过程

监督员

myMailer:myMailer_00           RUNNING    pid 16847, uptime 0:01:41
myMailer:myMailer_01           RUNNING    pid 16846, uptime 0:01:41
myMailer:myMailer_02           RUNNING    pid 16845, uptime 0:01:41

那么为什么我们需要使用proc_open（）函数呢

supervisorctl start all

myMailer_02: started
myMailer_01: started
myMailer_00: started

myImages_02: started
myImages_01: started
myImages_00: started

myMailer:myMailer_00           RUNNING    pid 16847, uptime 0:01:41
myMailer:myMailer_01           RUNNING    pid 16846, uptime 0:01:41
myMailer:myMailer_02           RUNNING    pid 16845, uptime 0:01:41
