to get unique value from multi dimensional array use this instead of array_unique(), because
array_unique() does not work on multidimensional:
array_map("unserialize", array_unique(array_map("serialize", $array)));
Hope this will help someone;
Example
$a=array(array('1'),array('2'),array('3'),array('4));
$b=array(array('2'),array('4'),array('6'),array('8));
$c=array_merge($a,$b);
then write this line to get unique values
$c=array_map("unserialize", array_unique(array_map("serialize", $c)));
print_r($c);
