Loop through your array and assign those years to a new array with their keys intact.

$years=array();
foreach($yourArray as $key=>$value)
{
   $years[$key]=$value["Culture"]["year"];
}
$years = array_unique($years);
print_r($years);

+1 for using $key=>$value instead of just $value

You can first loop through the array with a foreach loop and then use array_unique to get the array of years:

$years = array();
foreach ($records as $record) {
    $years[] = $record['Culture']['year'];
}
$years = array_unique($years);

Demo!

$years = [];
foreach($arr as $newarray){
  $years[] = $newarray['Culture']['year'];
}
$years = array_unique($years);

The new array years will now hold all the years in the old array. array_unique will get rid of all duplicate years.

My way is to use array-walk that takes anonymous function to fill the array, the solution will be in only one line of code.

Its working for me

    foreach($cultures as $row)
    {
        $year[]=$row['Culture']['year'];
    }
    $year = array_unique($year);
    $year = array_values($year);
    echo "<pre>";print_r($year);

what does using array_values twice achieve? Also, this is the same as the above answers.

yes Mr D, your code is right and array_values is here for re-index array, but am changing it, thanks for your answer
