This article will introduce to you the implementation method of sorting object arrays by object fields in PHP.
Given an array of objects, we sort the array by objects and given fields.
Method:
usort() function is a built-in function in PHP that is used to conditionally sort an array of elements using a given comparator function. The usort() function can also be used to sort an object array by object fields.
