PHP基于yii框架实现生成ICO图标
1，phpthumb_ico是生成ICO图标的类，源码如下

$icXOR[$key]='';
for($y=$ImageHeights[$key]-1;$y>=0;$y--){
for($x=0;$x<$ImageWidths[$key];$x++){
$argb=$this->GetPixelColor($gd_image,$x,$y);
$a=round(255*((127-$argb['alpha'])/127));
$r=$argb['red'];
$g=$argb['green'];
$b=$argb['blue'];
if($bpp[$key]==32){
$icXOR[$key].=chr($b).chr($g).chr($r).chr($a);
}elseif($bpp[$key]==24){

}
if($a<128){

}

2，后台
引入类：
Yii::$enableIncludePath=false;
Yii::import('application.extensions.ico.phpthumb_ico',1);
解决生成黑色背景的问题
imagealphablending($resize_im,false);//不合并颜色,直接用$im图像颜色替换,包括透明色
imagesavealpha($resize_im,true);//不要丢了$resize_im图像的透明色
