Question

What i am trying to work out is it bad practice instantiate a class like

new Classname();

As i need to run the classes __construct but i do not need to use the class past that. as other functions within the class will be called from the __construct.

Answer 1

It’d work, but, as someone maintaining your code, I’d be super confused by that. Generally, merely instantiating an object has no side-effects, so I’d assume that I could just delete that line and everything would still work fine.

I’d recommend reconsidering your code’s structure, since putting code with side-effects in __construct is definitely not standard.
