然后它就消失了，直到它再次被设定。如果需要动态索引数组，请查看

array\u values（）

函数。您可以

unset（$array\u disordination[$a][0]），记得吗？只删除该值，而不重新为数组编制索引；它甚至不知道您要求它取消设置的值在数组中，它也不会在意，因为关心数组不是它的工作。也不会对数组重新编制索引。它只找到最大的数字键，将其递增并将值存储在其中。无需使用array\u push或
$array48[0][]=array\u shift（$array48[0]）是的，无论哪种方式：）都不需要数组推送
$array48[0][]=数组移位（$array48[0]）是的，无论哪种方式：）
