我有一个数组，其中的vehicle_code、year和vehicle_code在数组中的同一年重复。我想删除数组中重复的vehicle_code和year值。我尝试了许多数组函数，如in_array array_column array_search等。但所有示例仅显示如何删除1列中的重复项，但我需要比较每组中两列的值。

0 => array:2 [
    0 => "AUA3H147"
    1 => 2015
    2 => Audi
    3 => 12457
  ]
  1 => array:2 [
    0 => "AUA3H147"
    1 => 2015
    2 => tata
    3 => 16832545
  ]

  2 => array:2 [
    0 => "AUA3H148"
    1 => 2016
    2 => tata
    3 => 55555
  ]
  3 => array:2 [
    0 => "AUA3H148"
    1 => 2017
    2 => Audi
    3 => 55555
  ]

我需要像下面这样的输出：

0 => array:2 [
    0 => "AUA3H147"
    1 => 2015
    2 => Audi
    3 => 12457
  ]
  1 => array:2 [
    0 => "AUA3H148"
    1 => 2016
    2 => tata
    3 => 16832545
  ]
  2 => array:2 [
    0 => "AUA3H148"
    1 => 2017
    2 => tata
    3 => 55555
  ]

我试过

$newArray = array(); 
$addArrayValues = array(); 
$priceVehicleYearCounter = 0
foreach ( $excelPriceArr as $key => $line ) { 
if ( (!in_array($line[0], $addArrayValues)) && (!in_array($line[1], $addArrayValues)) ) { 
      $addArrayValues[$priceVehicleYearCounter] = array(
      'id' => $priceVehicleYearCounter,
      'vehicle_code' => $line[0],
      'year' => $line[1],
      );
      $priceVehicleYearCounter++;
      $newArray[$priceVehicleYearCounter] = $line; 
   }
}

我看到了相同的单列搜索示例，我修改了它以搜索两个值，但它不起作用

if(array_search($line, array_column($addArrayValues, 'vehicle_code','year')) == false) {
                                $addArrayValues[$priceVehicleYearCounter] = array(
                                    'id' => $priceVehicleYearCounter,
                                    'vehicle_code' => $line[0],
                                    'year' => $line[1],
                                );
                                $priceVehicleYearCounter++;
                                $newArray[$priceVehicleYearCounter] = $line;
                            }

也是这样：

$result = array_unique($addArrayValues, SORT_REGULAR);

$result = array_map("unserialize", array_unique(array_map("serialize", $addArrayValues)));
