Question

我需要帮助才能理解如何使用PHP进行inotify工作。我有一个主文件，我调用我创建的inotify类的实例。

这工作30秒然后php抛出超时错误。在那个时间窗口中，它实际上可以打印来自新文件和已删除文件的信息。它有点工作，但......

我对你们的问题是：

我怎样才能使它持久稳定。我的意思是我可以设置无限时间的超时请求，但这似乎不是一个好习惯。怎么处理这个？
它应该像这样工作？我调用函数和php 在这个循环中挂起，直到发生新的变化？

我的index.php

$teste = new Inotify_service();

$teste->add_watch('files');

class Inotify_service
{
    private $instance;  
    private $watch_id;

    public function __construct()
    {
        $this->instance = inotify_init();
        stream_set_blocking($this->instance, 0); # this is needed so inotify_read while operate in non blocking mode
    }

    /**
     * [add_watch Adds a new watch or modify an existing watch for the file or directory specified in pathname]
     * @param [string] $pathname [description]
     */
    public function add_watch($pathname)
    {
        $this->watch_id = inotify_add_watch($this->instance, $pathname, IN_CREATE | IN_DELETE);

        while(true){

            // read events 
            $events = inotify_read($this->instance);

            // if the event is happening within our 'Files directory'
            if ($events[0]['wd'] === $this->watch_id){
                // a file was created
                if($events[0]['mask'] === IN_CREATE){
                printf("Created file: %s in Files directory\n", $events[0]['name']);
                // a file was deleted
                } else if ($events[0]['mask'] === IN_DELETE){
                    printf("Deleted file: %s in Files directory\n", $events[0]['name']);
                }                   
            }
        }

        // stop watching our directories
        inotify_rm_watch($this->instance, $this->watch_id);
        // close our inotify instance
        fclose($this->instance);
    }

使用php和inotify跟踪文件夹
