I have this code, but i want in second loop a decrease of $p value. The first internal loop must be repeated three times, the second, two times and the last, one time. I am trying $p-- but without success.

Any idea ? thanks

```
$p = 3;
for ($i = 0; $i < 3; $i++) {
     for ($o = 0; $o < $p; $o++) {
          echo "something";
          $p--;
     }
}

```
