Push to array

Question

Hello.
I need to push data from one array to another, but if first array has two identical values, it shouldnt be added.
$arr1 = [
[ ‘date’ => ‘november’, visits: ‘140’],
[ ‘date’ => ‘oktober’, visits: ‘120’],
[ ‘date’ => ‘november’, visits: ‘96’],
];

The second array should be :
$arr2 = [
[ ‘date’ => ‘november’, visits: ‘140’],
[ ‘date’ => ‘oktober’, visits: ‘120’],
];
