Convert MIME type to file Extension PHP

I've been looking around in the PHP documentation for some time, but I found no way to convert a MIME type extension to a file type extension.

image_type_to_extension

Seems to work if the file is an image. In my particular case, the mime types are not for images, they are for font types: 'otf, ttf'.

Solution

  • You could use something like:

    function getExtension ($mime_type){

    $extensions = array('image/jpeg' => 'jpeg',
                        'text/xml' => 'xml'
                       );

    // Add as many other Mime Types / File Extensions as you like

    return $extensions[$mime_type];

}

    Note: not every MIME type has a fixed file extension. Also, MIME types like application/octet-stream can refer to multiple file extensions.
