Two-dimensional arrays remove duplicate values and Array_unique functions

Today, the problem is that the array removed from the database is a two-dimensional array, now is the two-bit array to go to the weight, but in PHP, for a one-dimensional array, we can directly use the PHP system function Array_unique, but this function does not remove the multidimensional array to duplicate , so I need to write myself a function to remove the duplicate values of the two-dimensional array.

1 functionARRAY_UNIQUE_FB ($array 2D){ 2 3     foreach($array 2D  as $v){4         $v=Join(‘,‘,$v);//dimension, you can also convert one-dimensional array to a comma-concatenated string using implode5 6         $temp[]=$v;7 8     }9 Ten     $temp=Array_unique($temp);//Remove duplicate strings, that is, duplicate one-dimensional arrays One  A     foreach($temp  as $k=$v){ -  -        $temp[$k]=Explode(‘,‘,$v);//re-assemble the disassembled array the  -     } -  -     return $temp;
