How to prefix a positive number with plus sign in PHP

I have code similar to this

$points = -2;
$points = +2;

I want to display them as strings including the – or +. This works fine for the – but not for the +

I have tried this to try to get the positive sign

echo (string)$points;

Any ideas?

The positive sign is omitted because if a number isn’t negative, it’s positive.

You’ll have to use a function of sorts:

function format_sign($number) {
  $number = int($number);

  if ($number > 0) {
    return "+" . $number;
  } else {
    return $number;
  }
}

And you can use it like this:

$n = -10;

echo format_sign($n);

Nope, I lied. sprintf() seems like a better solution:

function format_sign($number) {
  return sprintf("%+d", $number);
}
