This is my object

$User = DB::table('user_app')
                ->where('id',$request->get('token'))
                ->select('account_type','address','card_bank','code_melli','shahr as city','family','id','mobile','name','phone','role','ostan as state','zip_code')
                ->first();

This is my json respons

"user_data": {
        "account_type": "real",
        "address": "سناباد",
        "city": null,
        "family": "حسینی",
        "id": 180,
        "mobile": "09371521106",
        "name": "الهام",
        "phone": "0513845555",
        "role": "usual",
        "state": {
            "id": 11,
            "name": "خراسان رضوی"
        },
        "zip_code": "91387"
    }

Now i want to put null property empty string for example instead of city put "" value for APIs... How could i do it

  • You can use a middleware which converts the json to array, and use array_walk_recursive to convert all null to empty string, and then convert back to JSON . This shall take care of all your APIs at one go Commented Jul 19, 2020 at 7:13
