迭代时更改 eloquent 对象值

Question

为了简化问题，当我遍历 eloquent 查询返回的对象数组时，当我尝试更改其中一个属性时，它似乎正在更改它们的所有属性。

假设 fruits 是 eloquent 查询返回的数据

var fruits =[{name:apple,nested_relationship:{price:$5},{name:pear,{price:$6},{name:grape}]

foreach ($fruits as fruit){
  if($fruit->name == 'apple'){
     $fruit->nested_relationship->color = 'red';
  }
  elseif($fruit->name == 'grape'){
     $fruit->nested_relationship->color = 'green';
  }
}

最后的结果好像是[{name:'apple',nested_relationship:{price:$5,color:'green'}},{name:pear,nested_relationship:{price:$5,color:'green'}},},{name:'grape'}]

谁能告诉我这是怎么回事？

Answer 1

试试这个解决方案：

使用 setAttribute() 添加新属性。

var fruits =[{name:apple,nested_relationship:{price:$5},{name:pear,{price:$6},{name:grape}]

foreach ($fruits as $fruit){
  if($fruit->name == 'apple'){
     $fruit->nested_relationship->setAttribute('color', 'red');
  }
  elseif($fruit->name == 'grape'){
     $fruit->nested_relationship->setAttribute('color', 'green');
  }
}
