SOLVED: See next post.

I am trying to strip all the chars after the period. the value will range from being 3-4 chars, so i cant simply limit the string length. is there a function that will help me do this?

SOLVED:

// Remove chars after . (200.000 => 200)
function removeDotZero($var)
{
    $var = trim($var);

    $pos = strpos($var,".");
    if($pos != false)
    {
        $size = strlen($var);

        for($i = $size; $i > $pos; $i--)
        {
            if(substr($var,-1,1) == "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9")
                $var = substr($var,0,($i - 1));
            else if(substr($var,-1,1) == ".")
            {
                $var = substr($var,0,($i - 1));
                break;
            }
            else
                break;
        }

        return $var;
    }
    else
        return $var;
}

Hmmm, why not use a native php function ?
http://www.php.net/manual/en/function.number-format.php

Or if you want to do it your way:

PHP Code:

function removeDotZero($var){
  $ret=null;
  $dotPos=strrpos(".",$var);  //Catch the last dot
  if($dotPos!==FALSE){  // !== and === test the type AND the value, here that the return is false, and not 0
    $ret=substr($var,0,-$dotPos);  //Cut your string until the position of the last dot
  }
  return $ret;
}

actually, i just used that function, and its doing exactly what i needed it to...1 step further than my other listed function, thanks!

If you're only working with numbers, you could also use the floor() function.
