Question

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.

Answer 1

Array assignment always involves value copying.

Use the reference operator to copy an array by reference.
