I have installed the XAMPP on my computer and a while ago I had to work with SQL Server, investigate in Google to be able to add SQL Server extensions to work with PHP and install everything right up there.
Now I had to work with another computer different from mine, I installed the XAMPP and everything worked fine but when I had to install the SQL Server extensions I started to get an error when starting the Apache.
the error comes to me about 4 times pressing "accept" and the Apache starts normal
The truth I did not find anything investigating about the error or something related, although the Apache starts it scares me that something can fail while I program.
Should I worry about this error?
How can I fix it?
I attach the dll files (extensions) of SQL Server and how to install them in case they find some anomaly because as I said above the error did not come out until after adding them.
These are the files already installed in the folder php/ext 
Finally this is the file PHP.ini where you had to specify the extensions so that they started using SQL Server next to PHP
