limpiar variable repedida

[ivan_mera13]

Hola tengo este array
Array
(
[0] => Array
(
[id] => 6
[name] => orckut
[amount] => 5
[reset] => 1
)

[1] => Array
(
[id] => 4
[name] => face
[amount] => 2
[reset] => 9
)

[2] => Array
(
[id] => 2
[name] => twitter
)

[3] => Array
(
[id] => 4
[name] => face
)

[4] => Array
(
[id] => 6
[name] => orckut
)

)

Quiero eliminar el valor repetido y mosytrarlo de esta manera he utilizado varias de las funciones de arrays() pero solo me devuelve la coincidencia y queiro que el resultado se muestre asi

Array
(
[0] => Array
(
[id] => 6
[name] => orckut
[amount] => 5
[reset] => 1
)

[1] => Array
(
[id] => 4
[name] => face
[amount] => 2
[reset] => 9
)

[2] => Array
(
[id] => 2
[name] => twitter
)

[3] => Array
(
[id] => 4
[name] => face
)
)
