csv files downloading as txt when using download attribute of <a> tag in PHP

I am trying to download File with csv extension using download attribute but it’s downloading file with .txt extension.

Here’s my code

<a href="log_files/log_files/abc.csv" download><button type="button" class="btn btn-success">Download</button></a>

Help me if you know the solution

>Solution :

<a href="log_files/log_files/abc.csv" download="abc.csv"><button type="button" class="btn btn-success">Download</button></a>
