Print out key/value of an object

I have an object

$vcpe =

{#298 ▼
  +"cpe_mac": "436291229311"
  +"bandwidth_max_up": 0
  +"bandwidth_max_down": 0
  +"filter_icmp_inbound": false
  +"dmz_enabled": false
  +"dmz_host": "192.168.1.1"
  +"vlan_id": 2
  +"dns": array:1 [▼
    0 => ""
  ]
  +"xdns_mode": 0
  +"cfprofileid": 11111
  +"stub_response": "0"
  +"acl_mode": 0
  +"portal_url": ""
  +"fullbandwidth_max_up": 1000000
  +"fullbandwidth_max_down": 2000000
  +"fullbandwidth_guaranty_up": 300000
  +"fullbandwidth_guaranty_down": 400000
  +"account_id": 1001
  +"location_id": 3333
  +"network_count": 3
  +"group_name": "test_group"
  +"vse_id": 20
  +"firewall_enabled": false
}

I want to loop through it, and print out the key, and the value.

Try#1

        @foreach ($vcpe as $key => $value)
          <p>{{$key}} : {{$value}}</p>
        @endforeach 

I got

htmlentities() expects parameter 1 to be string, array given

---

Try#2

        @foreach ($vcpe as $key => $value)
          <p>{!!$key!!} : {!!$value!!}</p>
        @endforeach

I got

Array to string conversion

---

Try#3

        @foreach ($vcpe as $key => $value)
          @foreach ($key as $k => $v)
            <p>{{$k}} : {{$v}}</p>
          @endforeach
        @endforeach

I got

Invalid argument supplied for foreach()

Can someone please show how do I print out all my key/value of an object ?
