Absent any actual need for choosing one method over the other, does passing arrays by value to a read-only function reduce performance compared to passing them by reference?
A Yes, because the interpreter must always create a copy of the array before passing it to the function.
B Yes, but only if the function modifies the contents of the array.
C Yes, but only if the array is large.
D Yes, because PHP must monitor the execution of the function to determine if changes are made to the array.
E No
