Answer 1

Using a single for loop:

$end = 5;
$out = array();

for ($i=0;$i<$end;++$i)
{
    $out[] = str_repeat('*', $i+1);
}
echo implode(PHP_EOL, $out).PHP_EOL;
array_pop($out);
$out = array_reverse($out);//remove last ****** <-- only one line with 5 stars
echo implode(PHP_EOL, $out).PHP_EOL;

Replace PHP_EOL with <br> if you want to, but this is the least loopy way to write this code I can think of
