Empty array values in array of objects using php - php

Question

I have an array like below.is there any way or one line code to empty all values inside array without foreach loop.
$array=json_decode('{
"client": "4",
"gateWay": "1",
"store": "store.shop.com",
"valid": "true",
"po": 34535,
"additionalPO": 23423,
"customerNotes": "",
"orderItems": [
{
"item": "123",
"quantity": 10,
"supplierLotNo": "",
"customsValue": "",
"customsDescription": "",
"hsCode": ""
},
{
"item": "345",
"quantity": 50
}
],
"shippingInfos": [
{
"address": {
"city": "Chennai",
"country": "India",
"postalCode": "86715",
"state": "TN",
"streetAddress1": "6971 North Street",
"streetAddress2": null
},
"contact": {
"company": null,
"email": "info#store.com",
"firstName": "test",
"lastName": "test",
"phoneNo": null
},
"ServiceId": "3",
"thirdPartyAccountNo": "",
"signatureConfirmation": false,
"saturdayDelivery": false
}
]
}',true);
The expected output should be I need empty string for string values,0 for integer values.
any help would be greatly appreciated.

You can do it with array_walk, assuming boolean is set to be NULL, here is the code.
Code
<?php
$array=json_decode('{
"client": "4",
"gateWay": "1",
"store": "store.shop.com",
"valid": "true",
"po": 34535,
"additionalPO": 23423,
"customerNotes": "",
"orderItems": [
{
"item": "123",
"quantity": 10,
"supplierLotNo": "",
"customsValue": "",
"customsDescription": "",
"hsCode": ""
},
{
"item": "345",
"quantity": 50
}
],
"shippingInfos": [
{
"address": {
"city": "Chennai",
"country": "India",
"postalCode": "86715",
"state": "TN",
"streetAddress1": "6971 North Street",
"streetAddress2": null
},
"contact": {
"company": null,
"email": "info#store.com",
"firstName": "test",
"lastName": "test",
"phoneNo": null
},
"ServiceId": "3",
"thirdPartyAccountNo": "",
"signatureConfirmation": false,
"saturdayDelivery": false
}
]
}',true);
($fx = function (&$in) use (&$fx) { is_array($in) ? array_walk($in, $fx) : ($in = is_string($in) ? "" : (is_int($in) ? 0 : NULL));})($array);
var_dump($array);
Output
array(9) {
["client"]=>
string(0) ""

string(0) ""

}
