If you don’t believe it, you can look for it where you can download the software. I guarantee you will not be disappointed. My words are not wrong. of.

The following is the original file of the program, the upload.php code is as follows:

<ol class="dp-j"><li class="alt"><span><span><table border=</span><span class="number">0</span><span> > </span></span></li><li><span> </span></li><li class="alt"><span><form enctype=multipart/form-data action=upsave.php method=post> </span></li><li><span> </span></li><li class="alt"><span><tr> </span></li><li><span> </span></li><li class="alt"><span><td>如果是*.zip的文件会被自动解压缩 </span></li><li><span> </span></li><li class="alt"><span><input name=myfile type=file size=<span class="number">50</span><span>> </span></span></li><li><span> </span></li><li class="alt"><span></td> </span></li><li><span> </span></li><li class="alt"><span></tr> </span></li><li><span> </span></li><li class="alt"><span><tr> </span></li><li><span> </span></li><li class="alt"><span><td colspan=<span class="number">2</span><span> align=center> </span></span></li><li><span> </span></li><li class="alt"><span><input type=submit value= 上传 <span class="keyword">class</span><span>=iwhite> </span></span></li><li><span> </span></li><li class="alt"><span><input type=reset value= 重填 <span class="keyword">class</span><span>=iwhite> </span></span></li><li><span> </span></li><li class="alt"><span></td> </span></li><li><span> </span></li><li class="alt"><span></tr> </span></li><li><span> </span></li><li class="alt"><span></table> </span></li><li><span> </span></li><li class="alt"><span></body> </span></li><li><span> </span></li><li class="alt"><span></html> </span></li><li><span> </span></li><li class="alt"><span>upsave.php代码如下: </span></li><li><span> </span></li><li class="alt"><span>代码如下: </span></li><li><span> </span></li><li class="alt"><span><?php </span></li><li><span> </span></li><li class="alt"><span><span class="comment">//保存上传的文件</span><span> </span></span></li><li><span> </span></li><li class="alt"><span>$filename=$myfile_name; </span></li><li><span> </span></li><li class="alt"><span>copy($myfile,$filename); </span></li><li><span> </span></li><li class="alt"><span>unlink($myfile); </span></li><li><span> </span></li><li class="alt"><span><span class="comment">//判断是否是zip文件</span><span> </span></span></li><li><span> </span></li><li class="alt"><span>$expand_name=explode(.,$filename); </span></li><li><span> </span></li><li class="alt"><span><span class="keyword">if</span><span>($expand_name[</span><span class="number">1</span><span>] == zip or $expand_name[</span><span class="number">1</span><span>] == zip) </span></span></li><li><span> </span></li><li class="alt"><span>{ </span></li><li><span> </span></li><li class="alt"><span>$str=pkunzip.exe -e $filename ; </span></li><li><span> </span></li><li class="alt"><span>exec($str); </span></li><li><span> </span></li><li class="alt"><span>unlink($filename); </span></li><li><span> </span></li><li class="alt"><span>} </span></li><li><span> </span></li><li class="alt"><span>> </span></li></ol>

I have tested the above program. It only needs to be placed on the server, but the directory must have write permissions, and a pkunzip.exe file must also be placed in the directory.

I hope this article will be helpful to everyone’s PHP programming design.
