Is there an automated way to determine the correct mimetype for each file attachment in PHP?

To determine the correct mimetype for each file attachment in PHP, you can use the `finfo_file()` function from the Fileinfo extension. This function returns the MIME type of a file based on its content. By using this function, you can automatically determine the correct mimetype for each file attachment in PHP. 

$file_path = 'path_to_your_file';
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$mime_type = finfo_file($finfo, $file_path);
finfo_close($finfo);

echo $mime_type;
