PHP program to print 5 to 15 without a loop

<?php
function printNumbers($current, $end) {
    if ($current > $end) {
        return;                       // stop
    }

    echo $current . "<br>";
    printNumbers($current + 1, $end); // call the function again
}

printNumbers(5, 15);
?>

Output:

How it works

• The function prints the current number, and then calls itself with the next number.
• When the current number becomes bigger than the end number, the if condition stops the function. This is called recursion.
