Removing duplicates from an array

[m7390]

I have a multidimensional array looking like this:\[code\]Array( [0] => Array ( [id] => 1 [genretitel] => actie [weekdag] => zaterdag [zaaltitel] => zaal 1 ) [1] => Array ( [id] => 5 [genretitel] => actie [weekdag] => zaterdag [zaaltitel] => zaal 1 ) [2] => Array ( [id] => 2 [genretitel] => animatie [weekdag] => zaterdag [zaaltitel] => zaal 1 ) [3] => Array ( [id] => 6 [genretitel] => komedie [weekdag] => zaterdag [zaaltitel] => zaal 1 ) [4] => Array ( [id] => 4 [genretitel] => animatie [weekdag] => zaterdag [zaaltitel] => zaal 2 ) [5] => Array ( [id] => 3 [genretitel] => drama [weekdag] => zaterdag [zaaltitel] => zaal 2 ) [6] => Array ( [id] => 8 [genretitel] => science fiction [weekdag] => zaterdag [zaaltitel] => zaal 2 ) [7] => Array ( [id] => 11 [genretitel] => avontuur [weekdag] => zaterdag [zaaltitel] => zaal 2 ) [8] => Array ( [id] => 15 [genretitel] => actie [weekdag] => zaterdag [zaaltitel] => zaal 3 ) [9] => Array ( [id] => 13 [genretitel] => animatie [weekdag] => zaterdag [zaaltitel] => zaal 3 ) [10] => Array ( [id] => 7 [genretitel] => documentaire [weekdag] => zaterdag [zaaltitel] => zaal 3 ) [11] => Array ( [id] => 10 [genretitel] => science fiction [weekdag] => zaterdag [zaaltitel] => zaal 3 ) [12] => Array ( [id] => 12 [genretitel] => actie [weekdag] => zaterdag [zaaltitel] => zaal 4 ) [13] => Array ( [id] => 14 [genretitel] => animatie [weekdag] => zaterdag [zaaltitel] => zaal 4 ) [14] => Array ( [id] => 9 [genretitel] => drama [weekdag] => zaterdag [zaaltitel] => zaal 4 ) [15] => Array ( [id] => 16 [genretitel] => historisch [weekdag] => zaterdag [zaaltitel] => zaal 4 ))\[/code\]What I would like to have is just the same multidimensional array but without the duplicates.
