Returns an associative array of strings representing the fetched row in the result

If two or more columns of the result have the same field names, the last
column will take precedence. To access the other column(s) of the same
name, you either need to access the result with numeric indices by using
<span class="function"><a href="mysqli-result.fetch-row.html" class="function">mysqli_fetch_row()</a></span> or add alias names.
