Answer / Devesh
In PHP, variables are passed by reference or by value depending on the context. In WordPress, when passing variables to functions, they are typically passed by reference. To explicitly pass a variable by value, you can use the `copy()` function:
```
$original_var = 123;
$copied_var = copy($original_var);
```
