                    (
                        [id] => 13
                        [title] => here title 4
                        [description] => here title 4
                        [year] => 2014
                        [photo] => here.JPG                        
                        [datetime] => 0000-00-00 00:00:00
                        [status] => 0
                    )

            )

        [5] => Array
            (
                [Culture] => Array
                    (
                        [id] => 14
                        [title] => here title 5
                        [description] => here title 5
                        [year] => 2015
                        [photo] => here.JPG                        
                        [datetime] => 0000-00-00 00:00:00
                        [status] => 0
                    )

            )               
    )

now from this array I want array of year (by key) like:

Array
(
[0]=>2012
[1]=>2013
[2]=>2014
[3]=>2015
)

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);

$years = [];
foreach($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.

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);

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);
