Is there a way to avoid overwriting long operands in if statements?

I constantly find myself if such statements look like this:

if(isset($this->request->data['Parent']['child'])){ $new_var['child'] = $this->request->data['Parent']['child']; }

My question is that without creating a new shorter variable before the if there a magical php process that can help avoid overwriting $this->request->data['Parent']['child'] in the body of the if statement? I also want the code to be clean for any successor developers.

I am also not looking for a triple solution. Something else a bit along the line of using jquery this . (What I know) php does not allow anonymous functions, or it is not a common practice, and I am not saying that I need a bunch of anonymous functions for all my classes.

It would be extremely cool, but, unfortunately, nothing can do it.
Perhaps some plugin for some IDEs can help you with this.

What I can offer in this case is what I do personally, without touching the mouse, moving the arrow cursor next to $this , then hold CTRL + SHIFT and the right arrow and you will choose most at a time . (Then just use ctrl + c and ctrl + v to copy the paste)

Of course this applies to all languages, not just PHP

 var $a = "" ; function __construct(){ if(isset($this->request->data['Parent']['child'])){ $this->a = "1"; } }

now use

 if(!empty($this->a)){ // ur code }

You can create a variable in the same condition block and use it after words

 if($child = $this->request->data['Parent']['child']){ $new_var['child'] = $child; }

The only difference here is that if $this->request->data['Parent']['child'] set but FALSE (or an empty string, NULL or 0), the test will fail

Although there are several ways to make your code shorter, I would advise against such methods. The reason is that most of these methods make the code much less comprehensible to the next person.

I would recommend using a good IDE with code completion, it would help to type long names, saving the code for the next person to look at it.

I'm not quite sure what you are really looking for, but you can use a custom object to store your data that does not generate notifications when trying to access non-existent keys.

 class Data { function __get($key) { return null; } }

This works because __get is only called when the key does not exist.
