Question

I have an array_flipped array that looks something like:

{ "a" => 0, "b" => 1, "c" => 2 }

Is there a standard function that I can use so it looks like (where all the values are set to 0?):

{ "a" => 0, "b" => 0, "c" => 0 }

I tried using a foreach loop, but if I remember correctly from other programming languages, you shouldn’t be able to change the value of an array via a foreach loop.

foreach( $poll_options as $k => $v )
  $v = 0; // doesn't seem to work...

tl; dr: how can I set all the values of an array to 0? Is there a standard function to do this?

Answer 1

You can use a foreach to reset the values;

foreach($poll_options as $k => $v) {
  $poll_options[$k] = 0;
}
