Question

I was practising statements and ran into a problem. I’m trying to make it so that if $child3 is available, then it will echo all three children, like how when $child2 is available, it echos Kim & Pom. What did I do wrong?

$child = "Kim";
$child2 = "Pom";
$child3 = "Rob";

if($child2) {
    echo $child; echo " "; echo $child2;
} elseif($child3) {
    echo $child; echo " "; echo $child2; echo " "; echo $child3;
} else {
    echo $child;
}

Answer 1

Try reversing the conditions:

$child = "Kim";
$child2 = "Pom";
$child3 = "Rob";

if($child3){
    echo $child . " " . $child2 . " " . $child3;
}else if($child2){
    echo $child . " " . $child2;
}else{
    echo $child;
}
