Question

我不知道从下面的嵌套数组中提取错误。我想知道我应该使用foreach来获取在树枝中显示的错误数组吗？

"errors" => FormErrorIterator {#1191 ▼
  -form: Form {#807 ▼
    -config: FormBuilder {#796 ▶}
    -parent: Form {#747 ▼
      -config: FormBuilder {#828 ▶}
      -parent: null
      -children: OrderedHashMap {#819 ▶}
      -errors: array:1 [▼
        0 => FormError {#1185 ▼
          -message: "Your first name must be at least characters long"
          #messageTemplate: "Your first name must be at least characters long"
          #messageParameters: array:2 [▶]
          #messagePluralization: 1
          -cause: ConstraintViolation {#1196 ▶}
          -origin: Form {#807}
        }
      ]
