Recursive php function with extra step

Question

I have the current recursive php funciton which actually uses curl (I've just simplifed the question here) and returns a json.

<?php
function getData($params = array(), $page = 1) {
if ($page == 1) {
 $xmlString = '{"result":{"current_page":1,"total_pages":3,"products":[{"name":"product1"},{"name":"product2"}]}}';
} else if ($page == 2) {
 $xmlString = '{"result":{"current_page":2,"total_pages":3,"products":[{"name":"product3"},{"name":"product4"}]}}';
} else if ($page == 3) {
 $xmlString = '{"result":{"current_page":3,"total_pages":3,"products":[{"name":"product5"}]}}';
}
if ($params['supplier_id'] == 13) {
 $products = [];
 $xmlArray = json_decode($xmlString, true);
 if ($xmlArray['result']['current_page'] < 3) {
 $nextPage = (int) $page + 1;
 $products = array_merge($xmlArray['result']['products'], getData($params, $nextPage));
 return $products;
 }
 $xmlString = $products;
}
$data['data'] = $xmlString;
$data['discount'] = isset($params['discount)']) ? $params['discount'] : 0;
$data['connection_user'] = isset($params['connection_user']) ? $params['connection_user'] : '';
return $data;
}
$params = '{"id": 1, "supplier_id": 13}';
$params = json_decode($params, true);
$data = getData($params);
echo "<pre>";
var_dump($data);

I would like for the $data['data'] to contain my products that came from my curl response, now I have something like this:

array(7) { [0]=> array(1) { ["name"]=> string(8) "product1" } [1]=> array(1) { ["name"]=> string(8) "product2" } [2]=> array(1) { ["name"]=> string(8) "product3" } [3]=> array(1) { ["name"]=> string(8) "product4" } ["data"]=> array(0) { } ["discount"]=> int(0) ["connection_user"]=> string(0) "" }

The response that I am looking for is something like:

array(3) { ["data"]=> array(5) { [0]=> array(1) { ["name"]=> string(8) "product1" } [1]=> array(1) { ["name"]=> string(8) "product2" } [2]=> array(1) { ["name"]=> string(8) "product3" } [3]=> array(1) { ["name"]=> string(8) "product4" } [4]=> array(1) { ["name"]=> string(8) "product5" } } ["discount"]=> int(0) ["connection_user"]=> string(0) "" }

• shajji: do you want to get all 5 products?
• shajji: or you just want to convert response into your desired response. like this array(7) {[0] => string(8) "product1" [1] => string(8) "product2" ...}
• J. Doe: I want to go through all the pages and get all the products and put all of them in $data['data']

Hope this help. Edited

<?php
 function getData($params = array(), $page = 1) {
 $data['data'] = getProducts($params, $page);
 $data['discount'] = isset($params['discount)']) ? $params['discount'] : 0;
 $data['connection_user'] = isset($params['connection_user']) ? $params['connection_user'] : '';
 return $data;
 }
 function getProducts($params = array(), $page = 1){
 if ($page == 1) {
 $xmlString = '{"result":{"current_page":1,"total_pages":3,"products":[{"name":"product1"},{"name":"product2"}]}}';
 } else if ($page == 2) {
 $xmlString = '{"result":{"current_page":2,"total_pages":3,"products":[{"name":"product3"},{"name":"product4"}]}}';
 } else if ($page == 3) {
 $xmlString = '{"result":{"current_page":3,"total_pages":3,"products":[{"name":"product5"}]}}';
 }else{
 $xmlString = '{"result":{"products":[]}}';
 }
 $xmlArray = json_decode($xmlString, true);
 $products = $xmlArray['result']['products'];
 if ($params['supplier_id'] == 13) {
 if ($page <= 3) {
 $nextPage = (int) $page + 1;
 $products = array_merge($products, getProducts($params, $nextPage));
 }
 }
 return $products;
 }
 $params = '{"id": 1, "supplier_id": 13}';
 $params = json_decode($params, true);
 $data = getData($params);
 var_dump($data);
?>

• J. Doe: after carefully looking at what you did, it's not what i needed. you simply changed the input into an array and looped it. I am using curl to get my info, and the result is paginated. that's why i did all the if else page. that's why i need recursion.
• shajji: i just did with recursion hope this help
• J. Doe: yes, now it works, sorry about the first time, was too exited. thank you for all your help.
