Ok.. How calculate if is in my range of attack? :S if my range example is 20

I only search for attack all enemy in this range :.. 1203.75,127.25 ... 1173.75,177.25 .. is in range of 20... help me pliss? :s
how calculate if my enemy if in this range

$dy = Enemy_Y - Player_Y
$dx = Enemy_X - Player_X
$dz = Enemy_Z - Player_Z
$3dDistance = sqrt($dy*dy + $dx*$dx + $dz*$dz) //on 3d games
$2dDistance = sqrt($dx*$dx + $dy*$dy)//2d games

Of course this works. Its just basic maths. It applys for all games, you just need to figure out where to get the 2d or 3d coordinates from.
