PHP怎么实现文件自动归类 PHP文件自动归类功能实现

<?php

// 监控的目录
$watchDir = '/path/to/your/directory';

// 创建 inotify 实例
$fd = inotify_init();

if ($fd === false) {
    die("Failed to initialize inotify");
}

// 添加监控
$watchDescriptor = inotify_add_watch($fd, $watchDir, IN_CREATE | IN_MODIFY | IN_DELETE);

if ($watchDescriptor === false) {
    die("Failed to add watch");
}

echo "Watching " . $watchDir . "...
";

while (true) {
    // 读取事件
    $events = inotify_read($fd);

    if ($events === false) {
        die("Failed to read events");
    }

    foreach ($events as $event) {
        // 忽略目录本身的变化
        if ($event['name'] == '') continue;

        $filename = $watchDir . '/' . $event['name'];

        if ($event['mask'] & IN_CREATE) {
            echo "File created: " . $filename . "
";
            // 在这里添加文件归类逻辑
        } elseif ($event['mask'] & IN_MODIFY) {
            echo "File modified: " . $filename . "
";
            // 在这里添加文件归类逻辑 (如果需要)
        } elseif ($event['mask'] & IN_DELETE) {
            echo "File deleted: " . $filename . "
";
        }
    }
}

// 移除监控
inotify_rm_watch($fd, $watchDescriptor);

// 关闭 inotify 实例
fclose($fd);
