php - 删除重复的数组php

Question

我有这样的脚本

foreach ($onerow as $onekey => $dt ){
$arr = array();
foreach($row as $classkey => $classfoto):
  $cek_class_foto = explode("/",$classfoto->name);
  if($dt->foto_naam!=$cek_class_foto[1]){ 
    $arr = array($dt->foto_naam);
    print_r(array_unique($arr));
  }
endforeach;
}

像这样的输出

Array ( [0] => _b101203.jpg ) 
Array ( [0] => _b101203.jpg )

我的问题是，如何删除这个重复数组？

谢谢

Answer 1

您正在覆盖$arr每次迭代。

foreach ($onerow as $onekey => $dt ){
    $arr = array();
    foreach($row as $classkey => $classfoto):
        $cek_class_foto = explode("/",$classfoto->name);
        if($dt->foto_naam!=$cek_class_foto[1]){ 
            $arr[] =$dt->foto_naam;
        }
    endforeach;
}
$arr = array_unique($arr);

$array1 = Array
            (
                '0' => Array
                    (

                        'userId' => 47,
                        'petId' => 68,
