私は同様の配列を持っています:

Array
(
[0] => Array
    (
        [id] => 1
        [name] => Mario
        [type] => Doctor
        [operations] => brain
        [balance] => 3.00
    )

[1] => Array
    (
        [id] => 3
        [name] => Luca
        [type] => Doctor
        [operations] => hearth
        [balance] => 6.00
    )

[2] => Array
    (
        [id] => 3
        [name] => Luca
        [type] => Doctor
        [operations] => hands
        [balance] => 4.00
    )

[3] => Array
    (
        [id] => 3
        [name] => Luca
        [type] => Doctor
        [operations] => foots
        [balance] => 1.00
    )

)

id をマージする必要があるため、配列 (0 と 1) の 2 つの要素のみを取得し、Luca (id 3) を操作用に統合する必要があります。分割されていません。

[...]
)
[1] => Array
(
  [id] => 3
  [name] => luca
  [type] => doctore
  [operations] => Array (6.00 hearts,
                         4.00 hands,
                         1.00 foots)

)

問題を解決する方法がわかりません...誰か助けてください。本当にありがとうございました！
