PHP create array from another array - php

Question

I have an array which I have received from an API.
object(stdClass)#19498 (4) {
["success"]=>
bool(true)
["quoteId"]=>
int(0011)
["abcValue"]=>
float(00)
["priceResponse"]=>
array(4) {
[0]=>
object(stdClass)#19502 (9) {
["priceId"]=>
int(1263)
["fPrice"]=>
float(37.14)
["grossPrice"]=>
float(44.7)
["priceType"]=>
string(2) "ABC"
}
[1]=>
object(stdClass)#19501 (10) {
["priceId"]=>
int(1263)
["fPrice"]=>
float(37.14)
["grossPrice"]=>
float(44.7)
["priceType"]=>
string(2) "ABC"
}
[2]=>
object(stdClass)#19500 (8) {
["priceId"]=>
int(1266)
["fPrice"]=>
float(550.14)
["grossPrice"]=>
float(544.7)
["priceType"]=>
string(2) "DEF"
}
}
}
I want to loop through the array to add another object in PriceResponse i.e customPrice and also delete some objects from the array like fPrice, priceType etc. The best way I figured to do this was to create another array. However I can't seem to get it working:
PHP:
$output_array = json_decode($output);
$modified_array = array();
$priceResultArray = array();
foreach($output_array as $j => $item) {
foreach($output_array->priceResponse as $i => $field) {
$percent = $field->grossPrice * 10 / 100;
$customPrice = $field->grossPrice + $percent;
$priceResultArray['priceId'] = $field->priceId;
$priceResultArray['customPrice'] = $customPrice;
}
$modified_array['success'] = $output_array->success;
$modified_array['quoteId'] = $output_array->quoteId;
$modified_array['priceResponse'] = $priceResultArray;
}
var_dump($modified_array);
This is the output of the modified array - it only shows the last result of the priceResultArray:
array(3) {
["success"]=>
bool(true)
["quoteId"]=>
int(0011)
["priceResult"]=>
array(5) {
["priceId"]=>
int(1266)
["customPrice"]=>
float(599.17)
}
}
Any pointers would be appreciated.

Answer 1

You don't need the outer loop. $output_array is a single object, not an array. You're looping over the properties, but never doing anything with $j or $item.
And instead of creating a new array, you can simply modify the objects in the original priceResponse array.
$output_array = json_decode($output);
foreach ($output_array->priceResponse as $field) {
$percent = $field->grossPrice * 10 / 100;
$customPrice = $field->grossPrice + $percent;
$field->customPrice = $customPrice;
unset($field->fPrice);
unset($field->priceType);
unset($field->grossPrice);
}

Answer 2

You have such output because you put values inside the same keys within your loop.
You should create new object on each loop interation.
Checkout this code:
$output_array = json_decode($output);
$modified_array = array();
$priceResultArray = array();
foreach($output_array as $j => $item) {
foreach($output_array->priceResponse as $i => $field) {
$percent = $field->grossPrice * 10 / 100;
$customPrice = $field->grossPrice + $percent;
$singlePriceResult = array();
$singlePriceResult['priceId'] = $field->priceId;
$singlePriceResult['customPrice'] = $customPrice;
$priceResultArray[] = $singlePriceResult;
}
$modified_array['success'] = $output_array->success;
$modified_array['quoteId'] = $output_array->quoteId;
$modified_array['priceResponse'] = $priceResultArray;
}
var_dump($modified_array);
