PHP Return Values from JSON Objects

Question

array(85) {
 [0]=>
 object(stdClass)#9 (18) {
 ["offer_id"]=>
 string(8) "12345678"
 ["offer_name"]=>
 string(39) "Offer Name"
 ["offer_desc"]=>
 string(209) "Offer Description"
 ["call_to_action"]=>
 string(57) "Offer CTA"
 ["offer_url"]=>
 string(80) "Offer URL"

 [1]=>
 object(stdClass)#11 (17) {
 ["offer_id"]=>
 string(8) "87654321"
 ["offer_name"]=>
 string(24) "Offer Name 2"
 ["offer_desc"]=>
 string(107) "Offer Description 2"
 ["call_to_action"]=>
 string(107) "Offer CTA 2"
 ["offer_url"]=>
 string(80) "Offer URL 2"
 ["offer_url_easy"]=>
 string(106) "Offer URL Easy 2"
 }

I am pulling a response from an API which contains an array with objects inside. I am trying to go through each object and get the value of each key.

For example I want to output: Offer ID: 12345678, Offer ID 2: 87654321

Currently my code is only outputting one ID (the first objects ID).

$arr = $offer_data->response->offers; //Outputs above array
foreach ($arr as $value) 
{
 return $value->offer_id;
}

Output: 12345678

Note: This is inside a function that I just echo.

Been trying different ways for hours, finally coming here. Thanks for any help you provide.

• Alex: Are you sure the JSON data is being interpreted as an associative array? If not it may just be a case of accessing the data like so; $value["offer_id"]

Answer 1

That's because you are returning at first iteration.

function test()
{
 $arr = $offer_data->response->offers; //Outputs above array
 $result = [];
 foreach ($arr as $value) {
 $result[] = $value->offer_id;
 }
 return $result;
}
$ids = test();
print_r($ids);

• user3451074: That's it! As I posted the question I found that doing the foreach outside of the function it would return as expected but inside, not. That's the answer I am looking for.

Answer 2

As of PHP 7(when it started to support objects as input) you can use array_column to extract all the values in one go...

return array_column($offer_data->response->offers, "offer_id");

Answer 3

Please try this.

$arr[] = $offer_data->response->offers;
