php对象数组怎么转换

$objectArray = [
    (object)['name' => 'John', 'age' => 30],
    (object)['name' => 'Mary', 'age' => 25],
];

// 转换为 JSON 字符串
$jsonString = json_encode($objectArray);

// 转换为 PHP 关联数组
$assocArray = json_decode($jsonString, true);

$objectArray = [
    (object)['name' => 'John', 'age' => 30],
    (object)['name' => 'Mary', 'age' => 25],
];

// 转换为序列化字符串
$serializedString = serialize($objectArray);

// 转换为 PHP 数组
$array = unserialize($serializedString);

$objectArray = [
    (object)['name' => 'John', 'age' => 30],
    (object)['name' => 'Mary', 'age' => 25],
];

// 将对象属性转换为数组键值对
$assocArray = array_map(function ($object) {
    return get_object_vars($object);
}, $objectArray);

$objectArray = [
    (object)['name' => 'John', 'age' => 30],
    (object)['name' => 'Mary', 'age' => 25],
];

// 创建关联数组
$assocArray = [];
foreach ($objectArray as $object) {
    $assocArray[] = (array) $object;
}
