What should I do if the php file is access denied and cannot be deleted?

The problem of PHP files being access denied and unable to be deleted is a rather tricky situation. It will not only affect the normal operation of our website, but also prevent us from operating these files. Below, I will introduce some solutions to help you solve this problem.

1. Check file permissions

Before we try to delete the file, we need to check the file permission settings. Some files may be set as read-only, in which case we cannot delete it. In order to solve this problem, we need to configure the permissions of the file to read and write. There are several ways to achieve this:

1. Use FTP tools

We can use FTP tools, such as FileZilla, etc., to log in to our website host and find the permissions we need to modify document. Just right-click the file, select "File Properties" and change it to "Readable and Writable".

2. Use the command line

You can modify permissions more quickly through the command line. We can log in to the host via SSH and enter the following command: chmod 777 file.php (where file.php is the name of the file we need to modify permissions). This command will set the file permissions to read, write, and executable.

2. Try to restart the server

Sometimes, after restarting the server, we can delete the files that are denied access. This is because some files may have been locked or in use and will be released after restarting the server. Of course, before restarting the server, we need to back up the website data to prevent data loss.

3. Use other tools to delete files

If the above two methods cannot solve the problem, we can consider using third-party tools, such as WinSCP, Total Commander, etc. These tools can delete files with higher permission levels and even delete some files that ordinary tools cannot delete.

4. Change the owner

Finally, we can try to change the owner of the file. Typically, in a Linux system, each file has an owner and one or more groups. If we are unable to delete the file, we can try changing the file owner. We can enter the following command via the command line: chown user file.php (where user is the new owner we want to give the file and file.php is the name of the file we are trying to delete).

Summary

The PHP file access denial and inability to delete is a troublesome problem, but we can easily solve it through the above methods. Before solving the problem, it is recommended to back up the website data to prevent data loss. If you have other solutions, please share.
