Linux virtual host space file or folder can not be deleted solution

When I maintain the blog file today, I found that I can't delete some folders and files in the website path through FTP. FTP prompt Permission Denied (no permission) makes me puzzled. I started looking for my own research ideas. Solution, since the FTP prompt permissions are insufficient, then it should be the problem in the file permissions setting of the server. I go to the server management background to view the file manager. The file manager displays the following figure:

It can be seen that the file owner generated by the PHP
program is the Apache account instead of my ftp account, so the Apache account has all the permissions to control these files but the FTP users do not, so I use my own on FTP. The user will delete the file system and will prompt me to delete them.

In order to determine the problem, I went to consult the server provider again. The answer is completely proof of my inference: general domestic Linux virtual host Apache and ftp are usually not in a user group, so the directory or file ftp created by apache can not be deleted, you must use php program to delete through Apache except.

How to solve it? Very simple, write a PHP program to complete this work
