Checking every 250 points in an if statement

So I want something where if they have 250 points they can level up, at 500 points they level again, then again at 750.

Would this work?

$levelup = $row['level'] * 250;

if ($levelup == TRUE)
{
//Process level up
}

$level = floor( $points / 250 );


< 250: level 0
>= 250: level 1
>= 500: level 2
>= 750: level 3, etc...

So you mean like this?

$points = $row['points'];
$level = floor($points / 250 );

if ($level >= 250)
{
//Process
}
else {
//Add Points
}

By the way I plan to reset their points to 0 on every level up.
