Question

I am new to the world of coding as well as PHP and am wondering how I can use return when looping. For example I would like to return/display 1-10 however not use echo.

$start = 1;
$end = 11;

for($start; $start < $end; $start=$start+1) {

echo $start; //how can I use return?

}

Well, return will exit the function, so if you put return in a loop, the loop will only do one iteration (until the return statement).

You can collect all the values in an array and return the array:

function myFunction() {
    $start = 1;
    $end = 11;
    $values = array();

    for($start; $start < $end; $start=$start+1) {
       $values[] = $start;
    }

    return $values;
}

That said, a function generating consecutive numbers already exists: range().
