使用PHP获取最近更新的文件

<?php
$directory = "path/to/directory"; // 替换为实际目录路径
$files = glob($directory . '/*');
$latest_ctime = 0;
$latest_filename = '';
foreach ($files as $file) {
    if (is_file($file)) {
        $ctime = filectime($file);
        if ($ctime > $latest_ctime) {
            $latest_ctime = $ctime;
            $latest_filename = $file;
        }
    }
}
echo "最近更新的文件是：" . $latest_filename . "，更新时间：" . date('Y-m-d H:i:s', $latest_ctime);
?>
