PHP生成ICO图标使用phpthumb_ico类完整实例 - 摘要: 本文讲的是PHP生成ICO图标使用phpthumb_ico类完整实例, 这里我使用的是yii框架。 1,phpthumb_ico 是生成ICO图标的类,源码如下 class phpthumb_ico { function phpthumb_ico() { return true; }

这里我使用的是yii框架。

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
