迭代通过多维对象/数组

Question

I have some data out of a soap api. This data comes in this format:

array(2) {
  ["Request"]=>
  object(stdClass)#7 (3) {
    ["AccessKey"]=>
    string(3) "dub"
    ["Timestamp"]=>
    string(19) "2019.07.04 09:06:19"
    ["Conditions"]=>
    object(stdClass)#8 (1) {
      ["Condition"]=>
      object(stdClass)#9 (2) {
        ["Field"]=>
        string(11) "From"
        ["Value"]=>
        string(10) "1562223979"
      }
    }
  }
  ["Products"]=>
  object(stdClass)#10 (1) {
    ["Product"]=>
    array(10) {
      [0]=>
      object(stdClass)#11 (11) {
        ["Ean"]=>
        string(13) "4029759107323"
        ["Type"]=>
        string(9) "DVD"
        ["Title"]=>
        string(58) "Hellraisers"
        ["FSK"]=>
        string(36) "Freigegeben ohne Altersbeschränkung"
        ["Genre"]=>
        string(5) "Sport"
        ["Year"]=>
        string(4) "2015"
        ["Length"]=>
        string(3) "275"
        ["Language"]=>
        string(7) "Deutsch"
        ["Items"]=>
        string(1) "2"
        ["Release"]=>
        string(10) "2049-12-31"
        ["Label"]=>
        string(17) "Edel Germany GmbH"
      }

I want to loop through this data and get the title of every set.

I tried a foreach loop, but I get some error messages.

foreach ($results as $result) {
    echo "Titel " . $result->Titel;
}

foreach ($results as $result) {
    echo "Titel " . $result['Product']->Titel;
}

Nothing works. I can't wrap my head around arrays...

When you don't grasp something, sometimes its better to try to make it small and grow from there, start trying to print the entire response, then the property products, then product and then the product array:

How to reach the products array inside $response

First you have an object $response has elements with objects inside, ["Products"] is the one we want, so $response->Products then inside ["Products"] there is an object, with one property with the name of ["Product"] that contains the array of objects with all the products, so $response>Products->Product. As $response->Products->Product is an array we need to iterate it, you iterate like this:

foreach($response->Products->Product as $product){
 echo $product->Title; // prints the title of every product
}

Don't hesitate to ask if you don't understand or it is not working, but by the code you pasted I thing the foreach is correct.

JSON format advice

By the way, the JSON is not "clear" and "correct", the array of products should be one level above. Inside "Products" and not inside "Product".
