Let us see Floyd’s Triangle with 13 Range Program in PHP.

<?php
$number = 0;
for ($i = 0; $i <= 12; $i++) {
    for ($j = 1; $j <= $i; $j++) {
        echo $number . "&nbsp&nbsp&nbsp;";
        $number++;
        if ($j == $i) {
            echo "&nbsp&nbsp&nbsp<br/>";
        }
    }
}
?>

<?php

$number = 0;

for ($i = 0; $i <= 12; $i++)
