使用列作为新的第一级键将对象的索引数组转换为对象的关联数组

$var是一个数组：

Array (
 [0] => stdClass Object ( [ID] => 113 [title] => text )
 [1] => stdClass Object ( [ID] => 114 [title] => text text text )
 [2] => stdClass Object ( [ID] => 115 [title] => text text )
 [3] => stdClass Object ( [ID] => 116 [title] => text )
)

想更新的话分两步：

• Get [ID]每个对象并将其值扔到位置计数器（我的意思是[0], [1], [2], [3])
• Remove [ID]投掷后

最后，更新数组（$new_var）应该看起来像：

Array (
 [113] => stdClass Object ( [title] => text )
 [114] => stdClass Object ( [title] => text text text )
 [115] => stdClass Object ( [title] => text text )
 [116] => stdClass Object ( [title] => text )
)

这个怎么做？

Thanks.

$new_array = array();
foreach ($var as $object)
{
  $temp_object = clone $object;
  unset($temp_object->id);
  $new_array[$object->id] = $temp_object;
}

我假设您的对象中有更多内容，而您只想删除 ID。如果你只想要标题，则不需要克隆到对象，只需设置$new_array[$object->id] = $object->title.
