Which of the following experts can help you modify the current code to back up mysql's php code and request it to be backed up locally?

Which of the following experts helped me modify the current code to back up mysql php code and asked me to back up it to a local location? I used php code circulating on the Internet to back up mysql data. The title of this article is: back up the php code of the mysql database (one table and one file ). The code is pasted at the bottom, but now it can only be backed up to the virtual host Directory. now I only need to back up to the local directory, such as a folder on the local computer D drive. The VM does not perform any operation, because I bought a paid vm. Which of the following experts helped me modify the current code to back up mysql php code and required to back up it to the local machine?

But now I can only back up to the virtual host Directory. now I only need to back up to the local directory, such as a folder on the local computer D drive. The VM does not perform any operation, because I buy a charged VM and it will not be able to afford long-term expenses. in addition to my php initial stage, slightly complicated code will not be modified.

You can check whether the code can be modified. you only need to back up the code locally. You can also provide me with code files with the same functions without modifying them. thank you.
