php multidimensional array unique

Comment

Using array_unique with SORT_REGULAR will return all unique arrays within an array.

$my_array=[
    array(1,2,3),                                                         
    array(1,2,3),                                                         
    array(1,2,4),                                                         
    array(1,2,5),                                                         
    array(1,2,5)                                                          
];                                                                        
$my_unique_array=array_unique($my_array,SORT_REGULAR);
