Return ACF Number Fields Formatted with Spaces instead of commas

Question

I have this code that helps me to add the comma between thousands but I need just a space instead of commas, how can I do this? I'm new to ACF and PHP as well, so just can't figure out how to do this, help me, please :( Should be something like this 20 000 instead of this 20,000

add_filter('acf/format_value/type=number', 'fix_number', 20, 3);
function fix_number($value, $post_id, $field) {
  $value = number_format($value);
  return $value;
}

Answer 1

Just in case someone needs this

add_filter('acf/format_value/type=number', 'fix_number', 20, 3);
function fix_number($value, $post_id, $field) {
  $value = number_format($value, 0, ',', ' ');
  return $value;
}
