PHP regular expression - filter number only

Question

I know this might sound as really dummy question, but I\'m trying to ensure that the provided string is of a number / decimal format to use it later on with PHP\'s number_fo

Answer 1

You could do something like this if you want only whole numbers.

function make_whole($v){
    $v = floor($v);
    if(is_numeric($v)){
      echo (int)$v;
      // if you want only positive whole numbers
      //echo (int)$v = abs($v);
    }
}
