StdClass Object to String , Iterating through the array - php

Question

Hi I've asked this before but didn't get a correct answer. I am trying to get the Tracks to print from the stdObject. I've tried many possible answers but nothing worked apart from using:
var_dump("Track Title: " .
$response->Items->Item->Tracks->Disc->Track[0]->_);
But this only works if you know how many tracks there are for certain CD, I am calling 500 ASIN's at once. So basically I would like to parse the Tracks array into a String
[Items] => stdClass Object
(
[Request] => stdClass Object
(
[IsValid] => True
[ItemLookupRequest] => stdClass Object
(
[IdType] => ASIN
[ItemId] => B000002OGL
[ResponseGroup] => Tracks
[VariationPage] => All
)
)
[Item] => stdClass Object
(
[ASIN] => B000002OGL
[Tracks] => stdClass Object
(
[Disc] => stdClass Object
(
[Track] => Array
(
[0] => stdClass Object
(
[_] => Mustang Sally
[Number] => 1
)
[1] => stdClass Object
(
[_] => Take Me To The River
[Number] => 2
)
[2] => stdClass Object
(
[_] => Chain Of Fools
[Number] => 3
)
[3] => stdClass Object
(
[_] => The Dark End Of The Street
[Number] => 4
)
[4] => stdClass Object
(
[_] => Destination: Anywhere
[Number] => 5
)
[5] => stdClass Object
(
[_] => I Can't Stand The Rain
[Number] => 6
)
[6] => stdClass Object
(
[_] => Try A Little Tenderness
[Number] => 7
)
[7] => stdClass Object
(
[_] => Treat Me Right
[Number] => 8
)
[8] => stdClass Object
(
[_] => Do Right Woman Do Right Man
[Number] => 9
)
[9] => stdClass Object
(
[_] => Mr. Pitiful
[Number] => 10
)
[10] => stdClass Object
(
[_] => I Never Loved A Man
[Number] => 11
)
[11] => stdClass Object
(
[_] => In The Midnight Hour
[Number] => 12
)
[12] => stdClass Object
(
[_] => Bye Bye Baby
[Number] => 13
)
[13] => stdClass Object
(
[_] => Slip Away
[Number] => 14
)
)
[Number] => 1
)
)
)
)
)

Answer 1

you can do
foreach($response->Items->Item->Tracks->Disc->Track as $track){
echo "Track Title: ". $track->_;// or track title
}
