 '''We have something that I have tested as follows:'''


 {{{
 $test_object = (object)array( 'var0' => 'ali', 'var1' => array( 'gaga' )
 );
 $test_array = array( 'var0' => 'varvar', 'var1' => array( 'googoo' ) );

 function append_baba( $value ) {
         return $value . 'baba';
 }

 error_log( 'BEFORE ' . var_export( $test_object, true ) );

 $output = map_deep( $test_object, 'append_baba'  );

 error_log(  'AFTER ' . var_export( $output, true ) );



 error_log( 'BEFORE ' . var_export( $test_array, true ) );

 $output = map_deep( $test_array, 'append_baba'  );

 error_log( 'AFTER ' . var_export( $output, true ) );
