PHP code snippet to determine the main color of a picture

This code can help you determine the main color of any picture, using a simple statistical algorithm to achieve

$i = imagecreatefromjpeg("image.jpg");

for ($x=0;$x< imagesx($i);$x++) {
 for ($y=0;$y $rgb = imagecolorat($i,$x,$y);
 $r = ($rgb >> 16) & 0xFF;
 $g = ($rgb >> & 0xFF;
 $b = $rgb & 0xFF;

 $rTotal += $r;
 $gTotal += $g;
 $bTotal += $b;
 $total++;
 }
}

$rAverage = round($rTotal/$total);
$gAverage = round($gTotal/$total);
$bAverage = round($bTotal/$total);
