?//URL後參加?pwd=密碼查看產生密碼 $password = '8baa717e6265d1c1d762cc896151f821' php ZIP 壓縮程式線上壓縮ZIP檔程式使用方法：選定要壓縮的檔案或目錄（包含子目錄），即可開始壓縮。壓縮的結果保留原來的目錄結構。 echo '当前目录：'. dirname(__FILE__) . ' 退出'; else if(isset($_GET['pwd']) ) echo '密码值：'. md5($_GET['pwd']) . ''; else echo 'Tips:在URL后参加?pwd=密码查看生成密码.'; ?> if(!isset($_REQUEST["myaction"])): ?>
驗證密碼:
	;

elseif($_REQUEST[" myaction"]=="dolist"):

if(!isset( $_REQUEST['pwd']) || empty($_REQUEST['pwd']) )

die('請輸入密碼! ');

if(md5($_REQUEST['pwd']) != $password)

die('輸入的密碼不正確！Again');

echo '選擇要排除的目錄(相對路徑，以英文半角逗號分隔):
';

echo '
';

echo "選擇要壓縮的檔案或目錄：
";

$fdir = opendir('./');

while($file=readdir($fdir)){

if($file=='.'|| $file=='..' ) continue;

echo " ";

if(is_file($file)){

echo "檔: $file
";

}else{

echo "目錄: $file
";

}

壓縮檔案儲存到目錄:

(留空為本目錄,必須有寫入權限)

壓縮檔案名稱:

(.zip)

elseif($_REQUEST["myaction"]=="dozip"):

// set_time_limit(0 );

class PHPzip{

var $file_count = 0 ;

var $datastr_len = 0;

var $dirstr_len = 0;

var $data = '' ; //變數只被類別外部程式存取

var $gzfilename;

var $fp;

var $dirstr='';

傳回檔案的修改時間格式.

只為本類內部函數呼叫.

function unix2DosTime($unixtime = 0) {

$timearray = ($unixtime == 0) ? getdate() : getdate($unixtime );

if ($timearray['year'] $timearray['year'] = 1980;

$timearray['mon'] = 1;

$timearray['mday'] = 1;

$timearray['hours'] = 0;

$timearray['minutes'] = 0;

$timearray['seconds'] = 0;

}

return (($timearray['year'] - 1980) ($timearray['hours'] > 1);

}

初始化檔案,建立檔案目錄,

並傳回檔案的寫入權限.

function startfile($path = 'myzip.zip'){

$this->gzfilename=$path;

$mypathdir=array();

do{

$mypathdir[] = $path = dirname($path);

}while($ path != '.');

@end($mypathdir);

do{

$path = @current($mypathdir);

@mkdir($path);

} while(@prev($mypathdir));

if($this->fp=@fopen($this->gzfilename,"w")){

return true;

}

return false; }

新增一個檔案到zip 壓縮包中.
