/**
|
||
* 网站源码一键压缩备份工具（增强版 v2）
|
||
*
|
||
* 兼容性：PHP 5.6+ / 7.x / 8.x 全系列
|
||
*
|
||
* v2 修复：
|
||
* - 修复 PHP 7.x 下 str_ends_with() / SIGKILL / fn() / ?? 等语法导致的 500
|
||
* - 修复大文件下载时 readfile() 撑爆 memory_limit 导致的 500
|
||
* - 下载前检查文件是否正在被写入（防下载不完整文件）
|
||
* - 关闭输出缓冲器 + 流式传输，支持 GB 级文件下载
|
||
*
|
||
* v3 改进：
|
||
* - 超时逻辑改为「自适应」：文件还在增长就不杀，文件不增长（卡住）才杀
|
||
* - 不再硬性限制压缩时间，大站压缩 30 分钟、1 小时都能正常完成
|
||
* - 前端显示「文件是否在增长」「写入速度」「距离上次写入过了多久」
|
||
* - 只有文件连续 STALL_TIMEOUT（60秒）不增长时才判定为卡死并终止

<strong>注意事项：</strong><br>
|
||
• 压缩过程完全在后台运行（nohup），关闭页面不会中断<br>
|
||
• 已自动排除 <code><?php echo htmlspecialchars($backup_dir); ?></code> 目录，避免重复备份<br>
|
||
• <strong>大小限制：</strong>不再提前拒绝，而是在压缩过程中实时监测，压缩文件超过 <?php echo $MAX_COMPRESSED_MB; ?> MB 时自动终止并保留已压缩部分<br>
|
||
• <strong>超时策略：</strong>超过 <?php echo formatSeconds($MAX_RUNTIME); ?> 后不会立即终止，只要文件还在增长就继续等待<br>
|
||
• 只有文件连续 <?php echo formatSeconds($STALL_TIMEOUT); ?> 不增长（真正卡死）才会自动终止<br>
|
||
• 如状态卡在"压缩中"，可点击"重置状态"按钮手动清除<br>
|
||
• <strong>v2 修复：</strong>兼容 PHP 5.6+ 全系列，下载使用流式传输不再撑爆内存
