PHP loop X amount of times

Question

I have a string called $columns which dynamically gets a value from 1 to 7. I want to create a loop of for however many times

Answer 1

just repeat $n times? ... if dont mind that $n goes backwards... the advantage is that you can see/config "times" at the beginning

$n = 5;
while (--$n >= 0)
{
  // do something, remember that $n goes backwards;
}
