_deprecated_constructor()
Marks a constructor as deprecated and informs when it has been used.
Similar to _deprecated_function(), but with different strings. Used to remove PHP4-style constructors.
The current behavior is to trigger a user error if WP_DEBUG is true.
This function is to be used in every PHP4-style constructor method that is deprecated.
Internal function — this function is designed to be used by the kernel itself. It is not recommended to use this function in your code.
Hooks from the function
Return
