How to remove duplicate values from an associative array based on a specific value?

Question

I have an array that looks just like that:

array(3) { [\"fk_article_id\"]=> string(1) \"4\" [\"first_name\"]=> string(6) \"Ulrike\" [\"last_name\"]=>         


        

Answer 1

** get Unique Associative Array ** using this method you can get easily unique Associative array /Multidimensional Array.

  array:6 [▼
     0 => array:1 [▼
       2 => "Airtel DTH"
           ]
      1 => array:1 [▼
      2 => "Airtel DTH"
           ]
      2 => array:1 [▼
      2 => "Airtel DTH"
           ]
      3 => array:1 [▼
      3 => "NeuSoft PVT LMT"
      ]
       4 => array:1 [▼
      3  => "NeuSoft PVT LMT"
       ]
      5 => array:1 [▼
       3 => "NeuSoft PVT LMT"
       ]
      ]


     function  assoc_Array_unique($array)
            {
                $result = array_map("unserialize", array_unique(array_map("serialize", $array)));

                foreach ($result as $key => $value)
                {
                    if ( is_array($value) )
                    {
                        $result[$key] = assoc_Array_unique($value);
                    }
                }
                return   $result;
            }
   $arr_Company=   assoc_Array_unique($arr_Company);  // get Unique Array 
                $arr_Company = array_values($arr_Company); Rearrange Index of Array.
