研究php的GD库的时候，发现了一段他人写的代码，这里给出来希望增加大家对php的热情。这段代码对人物头像进行了代码的马赛克，看起来很有趣。
function pixelfuck($url, $chars='ewk34543§G§$§$Tg34g4g', $shrpns=1, $size=4,$weight=2)
{
list($w, $h, $type) = getimagesize($url);
$resource = imagecreatefromstring(file_get_contents($url));
$img = imagecreatetruecolor($w*$size,$h*$size);
$cc = strlen($chars);
for($y=0;$y <$h;$y+=$shrpns)
for($x=0;$x <$w;$x+=$shrpns)
imagestring($img,$weight,$x*$size,$y*$size, $chars{@++$p%$cc}, imagecolorat($resource, $x, $y));
return $img;
}
$url = 'http://www.bkjia.com/uploads/allimg/140830/0421361239-0.png';
$text = 'I-dont-like-manga-...-Why-do-they-have-such-big-eyes? Strange-...-WHAT-WANT-YOU-DO?';
Header('Content-Type: image/png');
imagepng(pixelfuck($url, $text, 1, 6));下面一个是原图像，一个是经过处理后的图像。
