How can you use yield in a loop within a closure function to output results?

To output results from a closure function using yield in a loop, you can define a generator function within the closure that yields results for each iteration of the loop. This allows you to lazily generate and output values without having to store them all in memory at once. By using yield, you can efficiently process large datasets or perform complex calculations within the closure function. 

$closureFunction = function() {
    yield "Result 1";
    yield "Result 2";
    yield "Result 3";
};

$generator = $closureFunction();

foreach ($generator as $result) {
    echo $result . "\n";
}
