How can PHP developers ensure they are retrieving the correct MIME type for SVG files?

To ensure that PHP developers are retrieving the correct MIME type for SVG files, they can use the `finfo` extension in PHP to determine the MIME type of a file. By using the `finfo_file()` function with the `FILEINFO_MIME_TYPE` flag, developers can accurately identify the MIME type of SVG files.

// Path to the SVG file
$filePath = 'path/to/file.svg';

// Create a new fileinfo resource
$finfo = finfo_open(FILEINFO_MIME_TYPE);

// Retrieve the MIME type of the SVG file
$mime = finfo_file($finfo, $filePath);

// Close the fileinfo resource
finfo_close($finfo);

// Output the MIME type
echo $mime;
