Get value of a key from a Plugin Serialized array

Just found about plugin_api and using it, the above can be achieved with just below code:

/** If plugins_api isn't available, load the file that holds the function */
if ( ! function_exists( 'plugins_api' ) )
require_once( ABSPATH . 'wp-admin/includes/plugin-install.php' );

/** Prepare our query */
$call_api = plugins_api( ‘plugin_information’,
array(
‘slug’ => ‘i-recommend-this’
)
);

/** Display the results */
if ( is_wp_error( $call_api ) )
echo ‘

' . print_r( $call_api->get_error_message(), true ) . '

‘;
else
//echo ‘

' . print_r( $call_api, true ) . '

‘;
echo ‘

‘ . print_r( $call_api->downloaded, true ) . ‘

‘;
