How can I create a pyramid from using php?

Question

I need to create a pyramid using asterisks. I specify a value which becomes the base of the pyramid. The base contains as much asterisks as the value specified and the pyram

Answer 1

I think that the simplest solution is to create 2 loops with condition:

$n = 5; // specify how many rows you want to
$stars = 0;

for ($i = $n; $i > 0; $i--) {
    for ($j = 0; $j < $i + $stars; $j++) {
        if ($j < $i - 1) {
            echo " ";
        } else {
            echo "*";
        }
    }

    $stars += 2;
    echo "\n";
}

The output will be:

    *
   ***
  *****
