Switch case used as an alternative to if-else-elseif to make it simpler to write conditions that are long and repeative.

We use PHP Switch case as follows for the example mentioned earlier:

$sunlight = 0;

switch ($sunlight){
	case "0":
		echo "sunlight not present";
		break;
	case "1":
		echo "sunlight present";
		break;	
	
	default:
		echo "Not sure about sunlight";
		break;	
}

This could have done using if-else-elseif also. But, using switch case simplies writing our code and understanding it. Also, note the default case in the switch statement.
