How to access the properties of an object in php

php Method to access the attribute of the object (when the key name of the attribute is a number) {}

This article writes a way to ArrayMethod to convert into an object. The keys of this array are numbers (that is, the array is an indexarray). When accessing the object, $obj->1 is obviously misplaced. So what should we do? What about accessing numeric properties of an object?

$obj->{1} ; Represents the attribute value corresponding to the key 1 of the attribute of the access object $obj!
