PHP排序复杂多维数组
我一直在努力用PHP按“user_likes”和“created_time”对这个数组进行排序，我看了几个关于Stackoverflow的例子，但没有找到正确的语法。我希望订单从最“用户喜欢”开始，然后是“创建时间”，甚至不确定这是否可行。我一直在尝试array_multisort，但运气不佳PHP排序复杂多维数组,php,Php,我一直在努力用PHP按“user_likes”和“created_time”对这个数组进行排序，我看了几个关于Stackoverflow的例子，但没有找到正确的语法。我希望订单从最“用户喜欢”开始，然后是“创建时间”，甚至不确定这是否可行。我一直在尝试array_multisort，但运气不佳 Array ( [0] => Array (
