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")

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>

<font color="red">
(.zip)
