Can you monitor which file executes the SQL statement?

I have to take care of the project, the developer is not me, but found that the site may have a backdoor.
Data is often modified by people.
But a file can not be found in a file.
So I want to monitor which file performs the operation recorded down analysis.
Excuse me, is there any way?

Does your project use a database class?

Refers to the conn.php when the database operation is called.

The Include folder has db_mysql.class.php

First check if there are mysql_query in the file other than db_mysql.class.php
If there is, it is a place to be screened.

In the db_mysql.class.php file, the method name contains the query, execute, INSERT, UPDATE, fetch words in the method
Join

File_put_contents (' Log.txt ', Print_r (Debug_backtrace (), 1), file_append);

You can see from the file Log.txt where the SQL commands were executed.

Thank you. However, I found that some PHP files also use some of the SQL statements themselves. Can I just write it in config.php?

It's all about data like that.

That's what you didn't do as I said!
