Answer 1

You should use a for loop instead of a foreach loop like so:

for($i = 0; $i < count($children); $i+=2) {
    $child1 = $children[$i];
    $child2 = $children[$i+1];
    // print both
}

if you may have an odd number of children you have to check if $i+1 < count($children) before printing it.
