今天第一次配置好了Linux下的Apache+php+MySQL，于是乎小试了一下，做了一个文件上传系统，非常成功。应某人要求，把这个很简单的东西发了上来。（回某人：你不会的话自己去看http://www.w3school.com.cn/）
php里面的$_FILES可以轻松访问到提交上来的文件，然后在提交的客户端放上一个表单，直接提交给upload.php即可。要注意的是需要用move_uploaded_file来保存上传的文件，而且如果在Linux或者Mac系统下要注意下目录的访问权限。
附代码：upload.html
View Code 1 <html> 2 <head> 3 <title>Upload Files</title> 4 </head> 5 6 <div>Upload your files to server: (<=200KB) </div> 7 <br /> 8 9 <form action="upload_file.php" method="post" enctype="multipart/form-data"> 10 <label for="file">FileName:</label> 11 <input type="file" name="file" id="file" /> 12 <br /> 13 <input type="submit" name="submit" value="Submit" /> 14 </form> 15 </html>
