Thank you for the contribution. It has been approved.

• I approve this contribution but there may be some improvements like:
  • You could have stated that this is a new feature came with PHP 7.
  • You could have explain its isset() equivalent of the feature. like:

$variable = isset($var1) ? $var1 : $var2;

• Next time, please make sure that you provide any information you can with your simple tutorials like this.
