5,101 PointsIs PHP passing by reference?
I might be confusing with the JavaScript way of only passing objects by reference. So, my question is when we pass the old instance of the object to the local variable is it actually passing by reference? Thanks.

"By default, function arguments are passed by value (so that if the value of the argument within the function is changed, it does not get changed outside of the function). To allow a function to modify its arguments, they must be passed by reference.
To have an argument to a function always passed by reference, prepend an ampersand (&) to the argument name in the function definition:."

Hope this helps.

5,101 PointsAlright, so only using the ampersand C++ style reference we can pass by reference, in this case it will create only a copy of that object? Thanks
