La sortie d'impression dd() intégrée de Laravel est un peu difficile à comprendre

Collection {#279 ▼
  #items: array:7 [▼
    0 => Cate {#280 ▼
      +timestamps: false
      #guarded: array:1 [▶]
      #connection: null
      #table: null
      #primaryKey: "id"
      #perPage: 15
      +incrementing: true
      #attributes: array:5 [▶]
      #original: array:5 [▶]
      #relations: []
      #hidden: []
      #visible: []
      #appends: []
      #fillable: []
      #dates: []

      #with: []
      #morphClass: null
      +exists: true

    }
    1 => Cate {#281 ▶}
    2 => Cate {#282 ▶}
    3 => Cate {#283 ▶}
    4 => Cate {#284 ▶}
    5 => Cate {#285 ▶}
    6 => Cate {#286 ▶}
  ]
}

Comment générer un tableau simple print_r comme celui-ci ?

[0] => Array
    (
        [id] => 1
        [pid] => 0
        [name] => 安徽省
        [son] => Array
            (
                [0] => Array
                    (
                        [id] => 3
                        [pid] => 1
                        [name] => 合肥市
                        [son] => Array
                            (
                                [0] => Array
                                    (
                                        [id] => 4
                                        [pid] => 3
                                        [name] => 长丰县
                                    )

                            )

                    )

                [1] => Array
                    (
                        [id] => 5
                        [pid] => 1
                        [name] => 安庆市
                    )

            )

    )
La sortie d'impression
