升级最新版dedecms程序后如何去除Power by DedeCms字样

自从dedecms织梦系统更新到7.15日的版本，底部版权信息调用标签{dede:global.cfg_powerby/}会自动加上织梦官方的链接“Power by DedeCms”，可能很多人都想去除这样的内容，本文呢就提供一个方法，当然用dedecms的，还是尊重官方的行为，查找文件：dedesql.class.php在588行：

1 $arrs1 = array(0x63,0x66,0x67,0x5f,0x70,0x6f,0x77,0x65,0x72,0x62,0x79); 2 $arrs2 = array(0x20,0x3c,0x61,0x20,0x68,0x72,0x65,0x66,0x3d,0x68,0x74,0x74,0x70,0x3a,0x2f,0x2f, 3 0x77,0x77,0x77,0x2e,0x64,0x65,0x64,0x65,0x63,0x6d,0x73,0x2e,0x63,0x6f,0x6d,0x20,0x74,0x61,0x72, 4 0x67,0x65,0x74,0x3d,0x27,0x5f,0x62,0x6c,0x61,0x6e,0x6b,0x27,0x3e,0x50,0x6f,0x77,0x65,0x72,0x20, 5 0x62,0x79,0x20,0x44,0x65,0x64,0x65,0x43,0x6d,0x73,0x3c,0x2f,0x61,0x3e);

删除这段代码即可解决这个问题
