CVarRef var("12|23|34"); Array arr = var.toArray("|");
CVarRef var(123); Array arr = var.toArray();This code creates a CVarRef object "var" with the value 123. The toArray method is then called on the "var" object without any parameter. The resulting array "arr" will contain only one element: 123. The package library for this method could be the PHP C++ library, as it provides a CVarRef class and an Array class. However, there could be other libraries that also provide similar functionality.
