end expects an actual array variable as a parameter -


The array. This array is passed by reference because it is modified by the function. This means you must pass it a real variable and not a function returning an array because only actual variables may be passed by reference.


You need to assign the result of the explode() statement to a program variable and then supply that as the parameter to the end() statement.
