$myArray = array('1','1','1');
$results = array_unique($myArray);
if(count($results) == 1)
{
    echo"all value is duplicates";
}
else
{
    echo"all value is not duplicates";
}

Do a test run and see if all results are the same:

foreach ($array as $newarray){
    echo $newarray. '';
}

You can check for count(array_intersect($arr1, $arr2)) == 0

You could also use this check:

count(array_count_values($arr)) == 1

You can use the test:

count(array_unique($arr)) == 1;

Alternatively you can use the test:

$arr === array_fill(0,count($arr),$arr[0]);

$results = array_unique($myArray);
if(count($results) == 1){
   // $myArray is all duplicates
}
