在我的 symfony 項目中，我需要能夠在刪除重復項的同時合并多個對象數組。例如 ：數組 1：Array( [0] => Absence Object ( [id] => 1 [type] => TypeConge Object ([id] => 4, [nom] => "Maladie") [user] => User Object (......) [debut] => 12-11-2019 00:00:00 ) [1] => Absence Object ( [id] => 2 [type] => TypeConge Object ([id] => 5, [nom] => "CA") [user] => User Object (......) [debut] => 13-11-2019 00:00:00 ) [2] => Absence Object ( [id] => 3 [type] => TypeConge Object ([id] => 4, [nom] => "Maladie") [user] => User Object (......) [debut] => 11-11-2019 00:00:00 ) )陣列 2：Array( [0] => Absence Object ( [id] => 1 [type] => TypeConge Object ([id] => 4, [nom] => "Maladie") [user] => User Object (......) [debut] => 12-11-2019 00:00:00 ) [1] => Absence Object ( [id] => 8 [type] => TypeConge Object ([id] => 4, [nom] => "Maladie") [user] => User Object (......) [debut] => 17-11-2019 00:00:00 ) )輸出： Array( [0] => Absence Object ( [id] => 1 [type] => TypeConge Object ([id] => 4, [nom] => "Maladie") [user] => User Object (......) [debut] => 12-11-2019 00:00:00 ) [1] => Absence Object ( [id] => 2 [type] => TypeConge Object ([id] => 5, [nom] => "CA") [user] => User Object (......) [debut] => 13-11-2019 00:00:00 )我使用這段代碼來做到這一點：$demandes = $this->getDemandesValidateur($unUser, $search, $superValidation);$tabDemandes = array_merge($tabDemandes, $demandes);$tabDemandes = array_map("unserialize", array_unique(array_map("serialize", $tabDemandes)));但我的印象是，由于序列化和反序列化，它會導致錯誤。我得到了很好的決賽桌，但有些數據似乎無法使用。例如我不能打電話：$absence->getType()->getNom();它有時會返回 null。是因為我的代碼嗎？

根據 splash58 的評論，您可以使用array_column()然后合并數組，同時只保留第一項?？梢栽谶@里看到一個樣本。
<?php
$records = array(
array(
'id' => 2135,
'first_name' => 'John',
'last_name' => 'Doe',
),
array(
'id' => 3245,
'first_name' => 'Sally',
'last_name' => 'Smith',
),
array(
'id' => 5342,
'first_name' => 'Jane',
'last_name' => 'Jones',
),
array(
'id' => 5623,
'first_name' => 'Peter',
'last_name' => 'Doe',
)
);
$records2 = array(
array(
'id' => 2135,
'first_name' => 'John',
'last_name' => 'Doe',
),
array(
'id' => 3245,
'first_name' => 'Sally',
'last_name' => 'Smith',
),
array(
'id' => 5342,
'first_name' => 'Jane',
'last_name' => 'Jones',
),
array(
'id' => 5624,
'first_name' => 'Peter',
'last_name' => 'Doe',
)
);
$first = array_column($records, null, 'id');
$second = array_column($records2, null, 'id');
$third = $first + $second;
// if you want to reset indexes
// $third = array_values($third);
echo print_r($third);

你可以這樣做：
$result = [];
$array1 = [
[
"id" => 1,
"other_data" => "text1"
],
[
"id" => 2,
"other_data" => "text2"
],
[
"id" => 3,
"other_data" => "text3"
],
];
$array2 = [
[
"id" => 1,
"other_data" => "text1"
],
[
"id" => 8,
"other_data" => "text8"
],
];
$merge_array = function($array, $result) {
foreach($array as $element) {
$id = $element["id"]; //In your case it could be $element->getId()
if(!isset($result[$id])) {
$result[$id] = $element;
}
}
return $result;
};
$result = $merge_array($array1, $result);
$result = $merge_array($array2, $result);
print_r(array_values($result));
