說我有一個多維數組.例如：

Array (

[0] => Array (

[animal_id] => 5494

[animal_name] => "Suzy"

[animal_type] => "zebra"

[animal_location] => 0

[animal_awake] => 1

[animal_age] => 3 )

[1] => Array (

[animal_id] => 5494

[animal_name] => "Joshua"

[animal_type] => "panda"

[animal_location] => 5

[animal_awake] => 0

[animal_age] => 8 )

[2] => Array (

[animal_id] => 5494

[animal_name] => "Debra"

[animal_type] => "snake"

[animal_location] => 7

[animal_awake] => 1

[animal_age] => 3 )

[3] => Array (

[animal_id] => 5495

[animal_name] => "Caleb"

[animal_type] => "zebra"

[animal_location] => 0

[animal_awake] => 1

[animal_age] => 3 )

[4] => Array (

[animal_id] => 5495

[animal_name] => "Joshua"

[animal_type] => "panda"

[animal_location] => 5

[animal_awake] => 0

[animal_age] => 8 )

[5] => Array (

[animal_id] => 5495

[animal_name] => "Debra"

[animal_type] => "snake"

[animal_location] => 7

[animal_awake] => 1

[animal_age] => 3 )

[6] => Array (

[animal_id] => 5496

[animal_name] => "Emily"

[animal_type] => "zebra"

[animal_location] => 0

[animal_awake] => 1

[animal_age] => 3 )

[7] => Array (

[animal_id] => 5496

[animal_name] => "Joshua"

[animal_type] => "panda"

[animal_location] => 5

[animal_awake] => 0

[animal_age] => 8 )

[8] => Array (

[animal_id] => 5496

[animal_name] => "Debra"

[animal_type] => "snake"

[animal_location] => 7

[animal_awake] => 1

[animal_age] => 3 )

)

我想比較所有的蛇與蛇,以及所有的熊貓對抗熊貓的等(但不是對熊貓的蛇)并將獨特的元素放入一個數組(所有獨特的元素組成一個陣列),我將如何這樣做.因為它們是數組中的元素,所以我有點難過.此外,我不會事先知道會有多少種不同的類型.例如,有一次我可以通過Panda,Bear,Snake的多維數組傳遞 – 下一次我可以通過Bird,Cat,Panda,Zebra傳遞數組.

有任何想法嗎？

最終輸出

Array (

[0] => Array (

[animal_id] => 5494

[animal_name] => "Suzy"

[animal_type] => "zebra"

[animal_location] => 0

[animal_awake] => 1

[animal_age] => 3 )

[1] => Array (

[animal_id] => 5494

[animal_name] => "Joshua"

[animal_type] => "panda"

[animal_location] => 5

[animal_awake] => 0

[animal_age] => 8 )

[2] => Array (

[animal_id] => 5495

[animal_name] => "Caleb"

[animal_type] => "zebra"

[animal_location] => 0

[animal_awake] => 1

[animal_age] => 3 )

[3] => Array (

[animal_id] => 5495

[animal_name] => "Debra"

[animal_type] => "snake"

[animal_location] => 7

[animal_awake] => 1

[animal_age] => 3 )

[4] => Array (

[animal_id] => 5496

[animal_name] => "Emily"

[animal_type] => "zebra"

[animal_location] => 0

[animal_awake] => 1

[animal_age] => 3 )

)
