note 98192 added to function.imageline

Function drawing of a line by a brush uses midpoint circle algorithm..., if dullness I agree to remove :))) 

<?php
//function drawLine(resource$image,int $x0,int $y0,int $x1,int $y1,int $lineWidth,int $color)
function drawLine($image,$x0, $y0,$x1, $y1,$radius,$color)
{
  $f = 1 - $radius;
  $ddF_x= 1;
  $ddF_y = -2 * $radius;
  $x= 0;
  $y = $radius;
	imageline($image,$x0, $y0 + $radius,$x1, $y1 + $radius,$color);
 	imageline($image,$x0, $y0 - $radius,$x1, $y1 - $radius,$color);
	imageline($image,$x0 + $radius, $y0,$x1 + $radius, $y1,$color);
	imageline($image,$x0 - $radius, $y0,$x1 - $radius, $y1,$color);

  while($x< $y)
  {
    if($f >= 0)
    {
      $y--;
      $ddF_y += 2;
      $f += $ddF_y;
    }
    $x++;
    $ddF_x+= 2;
    $f += $ddF_x;
	imageline($image,$x0 + $x, $y0 + $y,$x1 + $x, $y1+ $y,$color);
   	imageline($image,$x0 - $x, $y0 + $y,$x1 - $x, $y1 + $y,$color);
   	imageline($image,$x0 + $x, $y0 - $y,$x1 + $x, $y1 - $y,$color);
   	imageline($image,$x0 - $x, $y0 - $y,$x1 - $x, $y1 - $y,$color);
   	imageline($image,$x0 + $y, $y0 + $x,$x1 + $y, $y1 + $x,$color);
   	imageline($image,$x0 - $y, $y0 + $x,$x1 - $y, $y1 + $x,$color);
   	imageline($image,$x0 + $y, $y0 - $x,$x1 + $y, $y1 - $x,$color);
   	imageline($image,$x0 - $y, $y0 - $x,$x1 - $y, $y1 - $x,$color);

  }
