php访问对象值

Question

stdClass Object
(
    [request] => stdClass Object
        (
            [other] => stdClass Object
                (
                    [4] => stdClass Object
                        (
                            [answer] => one
                        )

                    [5] => stdClass Object
                        (
                            [answer] => two
                        )

                    [6] => stdClass Object
                        (
                            [answer] => three
                        )
                )

        )
)
?>

I'm able to print out all the answers by looping with a foreach.

foreach( $result->request->other as $test )
      $tests[] = $test->answer;
            foreach($tests as $test1){
            echo "<p>$test1</p><br>";
          }

I'm a little confused on how to also echo out the answer number which in this case is 4 5 6. How do i echo them out as part of the loop. ex:

4 one
5 two
6 three

Answer 1

use foreach( $array AS $key=>$val ) syntax, like this:

foreach( $result->request->other as $key=>$test ) {
  printf( "<p>%s: %s</p><br />", $key, $test->answer );
}
