As you can see, the first element of the array after sorting is the minimum value, and the last element is the maximum value. You only need to delete these two values.

Step 2. Delete the maximum and minimum values (the first and last elements of the array)

So how to delete the first and last element of the array, you can use the array_pop () and array_shift () functions

Array_pop (): deletes the last element in the array (off the stack).

Array_shift (): deletes the first element in the array.

Array_pop ($arr); / / remove the maximum var_dump ($arr)

Array_shift ($arr); / / remove the minimum var_dump ($arr)

Note: the array_pop () and array_shift () functions modify the original array.
