如何从对象数组中解析数据

Question

I have an array of object $data in my code. I want to collect some of the object attribute to print in my web page. That's why I printed dump($data) so that I can see the pattern how the object and their attributes distributed in the array of object $data.

But I could not parse anything from that after seeing $data through the dump() function.

After using dump($data) I found something like...

array:1 [▼
  0 => {#238 ▼
    +"data_": 8
  }
]

I need "data_": 8 so that I can collect 8 from here. Why there is #238 ? What's the significance of it ?

Answer 1

The 238 should be the object id.

Try the following code:

foreach($data as $obj)
{
    echo $obj->data_;
}
