We are given an array with key-value pair, and we need to find the last value of array without affecting the array pointer.
Input : $arr = array('c1' => 'Red', 'c2' => 'Green', 'c3' => 'Blue', 'c4' => 'Black') Output : Black Input : $arr = array('p1' => 'New York', 'p2' => 'Germany', 'p3' => 'England', 'p4' => 'France') Output : France
The above problem can be easily solved using PHP. The idea is to create a copy of the original array and then use the array_pop() inbuilt function, to get the last value of the array. As we are using the array_pop() function on the copy array, so the pointer of the original array remains unchanged.
Built-in function used:
- array_pop(): The function is used to delete or pop the last element of an array.
Below is the implementation of the above approach:
Bangalore Array ( [c1] => Delhi [c2] => Kolkata [c3] => Mumbai [c4] => Bangalore )
