Question

How can I write this in such a way that $counter value is 1 on its first iteration and 0 on each following cycle?

$counter =1;

foreach($result):

 $number = $result['value'] + $counter;

 db->update($result['value'] => $number);

 $counter--;

endforeach;

Essentially my goal is to get $number to be $number+1 on the first loop and then $number+0 for each following loop.

The value of $result[‘value’] will be set after the first loop to $number+1, so on the next cycle $result[‘value’] will be the needed unchanged value.

Answer 1

I do not see where the problem resides.

$counter = 1;
foreach($result):
  $number = $result['value'] + $counter;
  // Once you have used your variable, just set it to zero...
  $counter = 0;
  db->update($result['value'] => $number);
endforeach;
