织梦dedecms删除Power by DedeCms的方法

不知道在哪一次版本升级后，织梦在预装网站里的网页底部加了个“Power by DedeCms”的字段，声明版权用的，然而站长在做站的时候，是不可能让这块显示的，删除方法如下：
领先步：打开文件include/dedesql.class.php
第二步：定位第588至592行的代码，将这些代码删除

代码如下：

$arrs1 = array(0x63,0x66,0x67,0x5f,0x70,0x6f,0x77,0x65,0x72,0x62,0x79);

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

删除之后保存就可以了
