PHP代码
复制代码 代码如下:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>网站程序备份</title>
</head>
<body>
<form name="myform" method="post" action="">
<?php
error_reporting(E_ALL & ~E_NOTICE);
ini_set(''memory_limit'', ''2048M'');
echo "选择要压缩的文件或目录:<br>";
$fdir = opendir(''./'');
while($file=readdir($fdir))
{
if($file==''.''|| $file==''..'')
continue;
echo "<input name=''dfile[]'' type=''checkbox'' value=''$file'' ".($file==basename(__FILE__)?"":"checked")."> ";
if(is_file($file))
{
echo "<font face=\"wingdings\" size=\"5\">2</font> $file<br>";
}
else
{
echo "<font face=\"wingdings\" size=\"5\">0</font> $file<br>";
}
}
?>
<br>
包含下列文件类型:
<input name="file_type" type="text" id="file_type" value="" size="50">
<font color="red">
(文件类型用"|"隔开,默认空则包含任意文件,例:如果需要打包php和jpg文件,则输入"php|jpg")
</font>
<br>
压缩文件保存到目录:
<input name="todir" type="text" id="todir" value="__dwb2011__" size="15">
<font color="red">
(留空为本目录,必须有写入权限)
</font>
<br>
压缩文件名称:
<input name="zipname" type="text" id="zipname" value="dwb2011.zip" size="15">
<font color="red">
(.zip)
</font>
<br>
<br>
<input name="myaction" type="hidden" id="myaction" value="dozip">
<input type=''button'' value=''反选'' onclick=''selrev();''>
<input type="submit" name="Submit" value=" 开始压缩 ">
<script language=''javascript''>

thiselm.checked = !thiselm.checked;
