PHP打包下载整个文件夹或多文件

有时候需要输出服务器上某个文件夹的全部文件，比如备份网站，用下面的PHP函数来实现。web开发 php

使用方法：

函数:文件压缩
压缩参数:需要压缩的文件或文件夹(文件可为数组),压缩后的zip文件名及存放路径,压缩类型1:文件夹2:文件,后续操作1:压缩后下载;2:存放在服务器上(默认为/@Upload下)
压缩文件夹示例:Tozip("./","../".date("d-H-i-s").".zip",1,2);
压缩文件示例:
$aaa=array("../1.txt","../2.txt");
Tozip($aaa,"../2.zip",2);

用法举例：
比如有这样一段文件结构：
home
--upload
----1.jpg
----2.jpg
----3.jpg
--web
----html
------inc
--------zip.php(这是上面的代码库）
------download.php

使用download.php中的代码，实现upload文件夹打包并自动下载：

<?php  Function Tozip($Path,$ZipFile,$Typ=1,$Todo=1){  //IF(!is_writeable($Path)){Exit("文件夹不可写!");}  $Path=Str_iReplace("\\","/",($Path)); IF(Is_Null($Path) Or Empty($Path) Or !IsSet($Path)){Return False;} IF(Is_Null($ZipFile) Or Empty($ZipFile) Or !IsSet($ZipFile)){Return False;} Include_once("inc/zip.php"); // 载入代码库，注意路径 $zip = New PHPZip; IF(SubStr($Path,-1,1)=="/"){$Path=SubStr($Path,0,StrLen($Path)-1);} OB_end_clean(); Switch ($Typ){ Case "1": $zip->ZipDir($Path,$ZipFile,$Todo); Break; Case "2": $zip->ZipFile($Path,$ZipFile,$Todo); Break; } IF($Todo==1){ Die(); }Else{ Return True; }
} Tozip("././upload", "../../upload.zip",1,1)
