Remove duplicate arrays from a 2D array. Takes an input 2D array and returns a new 2D array without duplicate arrays.

unique_array.php

<?php
function unique_array($multidimetionalarray) {
    $static_array = array();
    foreach($multidimetionalarray as $array){
        $static_array[] = json_encode($array);
    }
    $filtered_static_array = array_unique($static_array);
    $filtered_array = array();
    foreach($filtered_static_array as $array){
        $filtered_array[] = json_decode($array, true);
    }
    return $filtered_array;
}

Better use array_unique($array, SORT_REGULAR) which generate same result with less effort.
