proc_terminate無法終止進程怎麼辦？可能原因和解決方案分析

三、完整解決示例

</span><span><span class="hljs-variable">$descriptorspec</span></span><span> = [

        </span><span><span class="hljs-comment">// 如果還在運行，嘗試 SIGKILL</span></span><span>
        </span><span><span class="hljs-title function_ invoke__">proc_terminate</span></span><span>(</span><span><span class="hljs-variable">$process</span></span><span>, </span><span><span class="hljs-number">9</span></span><span>);
    }

    </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">// 清理資源</span></span><span>
}
</span></span>

四、其他可​​行替代方案

• 使用popen()和exec()配合外部kill命令管理進程。

• 在Linux 上使用pcntl_fork() （CLI 環境）自行實現進程管理。

• 對於復雜任務，考慮使用進程管理框架（如Supervisord）代替proc_open() 。
