PHP to remove duplicated values and exactly UNIQUE from multidimensional array -


i found many question , answer this, not match need. think it's similar/same this question don't know why not working case. please try before judging duplicates, thank you.

array source

$avar = array( 0 => array(1,2,3,4,5,6,7,8,9), 1 => array(10,11,12,13,14,15,16,17,7,8,9,10), 23 => array(21,22,23,4,5,6,7,11,12,13,14,15,21));

desired result

$avar = array( 0 => array(1,2,3,4,5,6,7,8,9), 1 => array(10,11,12,13,14,15,16,17), 23 => array(21,22,23));

php script

<?php function super_unique($array) {   $result = array_map("unserialize", array_unique(array_map("serialize", $array)));    foreach ($result $key => $value)   {     if ( is_array($value) )     {       $result[$key] = super_unique($value);     }   }    return $result; }  $result = super_unique($avar);   echo "<pre>"; print_r($result);  ?>

similar question answer not solve case:

  1. how remove duplicate values multi-dimensional array in php
