php - 合并两个包含对象的数组并删除重复值

Question

我需要将两个对象数组合并为 1 个数组并删除重复的 email 值。

我该怎么做？

这些是我的示例数组:

$array1 = [
    (object) ["email" => "gffggfg"],
    (object) ["email" => "wefwef@test.it"],
    (object) ["email" => "wefewf"],
];
$array2 = [
    (object) ["email" => "gffggfg@test.it"],
    (object) ["email" => "wefwef"],
    (object) ["email" => "wefewf"],
];

我的预期结果是:

[
   (object) ['email' => 'gffggfg'],
   (object) ['email' => 'wefwef@test.it'],
   (object) ['email' => 'wefewf'],
   (object) ['email' => 'gffggfg@test.it'],
   (object) ['email' => 'wefwef'],
]

Answer 1

您可以结合array_merge() array_unique() 的函数功能(两个标题都很不言自明)

$array = array_unique (array_merge ($array1, $array2));
