To sort an associative array based on its keys in descending order in PHP, you would use the krsort() function. The krsort() function sorts the elements of the associative array in descending order based on their keys. It rearranges the array elements in such a way that the keys are sorted in descending order while maintaining the association between keys and values. This function directly modifies the original associative array. Sorting an associative array by keys in descending order can be useful when you want to arrange the array based on the key order in a reverse sequence.
