Tip: Save it to a PHP file and open it in the browser to see a picture that is the same as the rendering.

Copy code The code is as follows:

$im=imagecreate(670,500);
$white = imagecolorallocate($im, 0xFF, 0xFF, 0xFF);
$g = imagecolorallocate($im, 0x00, 0x00, 0x00);
define("PII",M_PI/180);
function drawLeaf($g,$x,$y,$L,$a){

global $im;
$B = 50 ;
$C =9;
$s1 = 2;
$s2 = 3;
$s3 = 1.2;
if($L > $s1)
{
                                                                                   / $s2 * cos(($a + $B) * PII);
               $y2R = $y2 + $L / $s2 * sin(($a + $B) * PII); = $x2 +$L / $s2 * cos(($a - $B) * PII); ;

$x1 = $x + $L / $s2 * cos($a * PII);
$y1 = $y + $L / $s2 * sin($a * PII);
          $x1L = $x1 + $L / $s2 * cos(($a - $B) * PII);
          $y1L = $y1 + $L / $s2 * sin(($a - $ B) * PII);
          $x1R = $x1 + $L / $s2 * cos(($a + $B) * PII);
            $y1R = $y1 + $L / $s2 * sin (($a + $B) * PII);

ImageLine($im,(int)$x, (int)$y, (int)$x2, (int)$y2, $g) ;
           ImageLine($im,(int)$x2, (int)$y2, (int)$x2R, (int)$y2R, $g);
          ImageLine($im,(int)$x2 , (int)$y2, (int)$x2L, (int)$y2L, $g);
       ImageLine($im,(int)$x1, (int)$y1, (int)$x1L, ( int)$y1L, $g);
ImageLine($im,(int)$x1, (int)$y1, (int)$x1R, (int)$y1R, $g);

drawLeaf($g, $x2, $y2, $L / $s3, $a + $C);
drawLeaf($g, $x2R, $y2R, $L / $s2, $a + $B );
           drawLeaf($g, $x2L, $y2L, $L / $s2, $a - $B); a - $B);
drawLeaf($g, $x1R, $y1R, $L / $s2, $a + $B);
drawLeaf($g,300,500,100,270 );
header("Content-type: image/png");
imagepng($im);
