Ok guys, you surely want to kill me, but I so love PHP in this case

in C# it would have been:
if(!int.TryParse(strVal, out int intVal) && intVal != 2 && intVal != 3){
return;
}

in Swift:
guard let intVal = Int(strVal), intVal == 2 || intVal == 3 else{
return
}

for me being able to do that it will make a mess in my code, maybe its just me ...

@gitpush yes but I don't want to use try and catch 😀

@davide ooh that looks much better than try catch code, but doesn't it produce exceptions? Not a PHP dev just wondering

@gitpush These functions doesn't produce an exception. They return only a boolean value

never mind me, just saw the is_number function so no chance for an exception when parsing it to int

int val = 0;
std::from_chars(idOperation, std::next(idOperation, length), val);
if (val != 2 && val != 3) return;

Ruby:

return unless idOperation.is_a? Number
return unless [2,3].includes? idOperation.to_i

Haskell:

Just kidding, you never have to check that shit in Haskell.
