If you want to get the file mime type for a remote file and you have its URL, the function below can be used.
Example
If the remote file is a png image with a url of http://example.com/directory/image.png?ver=123, passing in that URL to this function would return image/png.
| <?php | |
| /** | |
| * Get the file mime type for a file by its URL. | |
| * | |
| * @param $url The URL to the file. | |
| * @return The file mime type or empty string on failure. | |
| */ | |
| function km_get_file_type_by_url( $url ) { | |
| $response = wp_remote_get( $url ); | |
| return wp_remote_retrieve_header( $response, 'content-type' ); | |
| } |
