How to use WordPress HTTP API to download file from remote location
Check out download_url() – it’s only loaded in the admin, so you’ll have to include it (or write your own) if needed on the front-end. From download_url() you can use: $response = wp_remote_get( TCS_CPDF_REMOTE_ZIP, array( ‘timeout’ => 300, ‘stream’ => true, ‘filename’ => TCS_CPDF_LOCAL_ZIP ) );
