Where have you provided this? I’ll reiterate my point that
If you actually have a valid argument or a point to make, this should be an incredibly easy request to respond to. If you don’t do this, you are are admitting you cannot.
By refusing to provide a code example you are simply admitting that you are incapable of doing so. Obfuscation and avoiding the question is just digging yourself further into a hole.
You keep using the word “appropriate” but you have never explained what you mean by that term. Similarly, you have never shown what solution you use in its place. If you want to use the word “Appropriate” you need to tell us what metric you are using to measure “appropriateness” and demonstrate a solution that is appropriate under that metric.
I want to re-answer this now the thread has reopened because this is a concept you really seem to be struggling with. And I genuinely think this is your sticking point.
You clearly fail to understand so I’ll make it even clearer as I can see that this is where you are failing to understand what DI is used for.
An object communicates with another object simply by call the object’s methods.
This statement presents a problem: How does one object know about another? In order to call a method on another object I must have a reference to it in a visible scope. So answer these questions:
- Do you have more than one object in your application?
- Does any one of those objects need to call a method on any other one of those objects?
- If yes to (1) and (2) assuming your objects are $a and $b and $b needs to call $a->foo(), how does the $b instance know about the $a instance in order to call the method?
One method of answering 3 is DI. If you answer yes to 1 and 2 you have the problem that DI solves. If you’re not using DI you are solving that problem in a different way, with another technique. Please explain, with code examples, that alternative technique and why you believe it is better suited to solving this problem than DI is. See #287 for an example of the format you should use to do this.
Once you’ve grasped that, and that if you’re not using DI to solve this problem you are using another technique go and re-read this thread from the start as it will be enlightening.
tl;dr Yes, you do have the problem that DI solves if you have more than one object and no amount of claiming otherwise will change that fact. As mentioned numerous times, “I don’t have the problem DI solves” is a factually incorrect claim.
