Why is mime_content_type() deprecated in PHP?

Question

I'm just curious to know why mime_content_type() is now considered deprecated.

This method for determining the mime type is much easier than the replacement Fileinfo functionality.

Answer 1

I guess it's because Fileinfo can return more information about files.

EDIT: Here is a replacement hack:

function _mime_content_type($filename) {
    $result = new finfo();
    
    if (is_resource($result) === true) {
        return $result->file($filename, FILEINFO_MIME_TYPE);
    }
    
    return false;
}
