In Drupal, an external link image is automatically obtained, and then extracted and uploaded to your website for function sharing.

Function get_external_image ($ url ){
$ External_image = file_get_contents ($ url );
$ Parsed_url = parse_url ($ url );
$ Name_dest = rand (1000,9999). "_". basename ($ parsed_url ["path"]);
$ File = file_save_data ($ external_image, 'public: // '. $ name_dest, FILE_EXISTS_REPLACE );
If (is_object ($ file) & file_exists ($ file-> uri )){
$ File-> status = 1;
$ File = file_save ($ file );
Drupal_write_record ('file _ usage', $ file );
Return (array) $ file;
}
Return null;
}
