如何从php中的二维数组中删除重复的数组

Question

[0] => Array
    (
        [event_date] => 2023-10-15
        [sale_id] => 11959
        [product_name] => 10x10 Commercial Pop-Up Tent | IMPACT Poly Top
        [product_id] => 14
        [qty_stock] => 3
        [qty_booked] => 10
        [qty_deficit] => -7
        [eventDate] => 2023-10-13
        [pickupDate] => 2023-10-16
    )

[1] => Array
    (
        [event_date] => 2023-10-15
        [sale_id] => 11959
        [product_name] => 10x10 Commercial Pop-Up Tent | IMPACT Poly Top
        [product_id] => 14
        [qty_stock] => 3
        [qty_booked] => 10
        [qty_deficit] => -7
        [eventDate] => 2023-10-15
        [pickupDate] => 2023-10-15
    )

我想要这里的一个数组元素。

[0] => 数组 （ [事件日期] => 2023-10-15 [销售 ID] => 11959 [product_name] => 10x10 商业弹出式帐篷 | IMPACT 聚酯纤维上衣 [产品 ID] => 14 [库存数量] => 3 [预订数量] => 10 [数量赤字] => -7 [活动日期] => 2023-10-13 [提货日期] => 2023-10-16 )
