    }

    </span><span><span class="hljs-title function_ invoke__">proc_close</span></span><span>(</span><span><span class="hljs-variable">$process</span></span><span>); </span><span><span class="hljs-comment">// 清理资源</span></span><span>
}
</span></span>

四、其他可行替代方案

使用 popen() 和 exec() 配合外部 kill 命令管理进程。
在 Linux 上使用 pcntl_fork()（CLI 环境）自行实现进程管理。
对于复杂任务，考虑使用进程管理框架（如 Supervisord）代替 proc_open()。
