Description:
------------
function myFunction($var1, $var2=3, $var3=4, $var4=5) {
echo $var1."\n".$var2."\n".$var3."\n".$var4;
}

Test script:
---------------
myFunction('Test Call', 3, 4, 10);

Expected result:
----------------
I expect this Output:

Test Call
3
4
10

Actual result:
--------------
Actual Same:
Test Call
3
4
10

But Issue is:
Now see that I only want to change $var4 value in my function. All other default values will remain same. But I have to remember every value and pass it through the function.

I am proposing a this change like this:

myFunction('Default Value', $var4=10);

so that Every developer can only pass value with specific variable name. This issue arises at many function when we used in our development. I think this change will be a big feature for developer.
