织梦dedecms调用网站版权信息是会出现powered by dedecms链接到www.dedecms.com这个网址，站在优化角度上来说，这种单向链出链接对我们来说多少有些不利，这里也是用织梦建站我们手动修改的一个地方，下面说说教程：

去掉powered by dedecms网站版权信息教程：

找到include/dedesql.class.php文件，用Notepad++或者DW(Dreamweaver)打开文件。

Ctrl+f查找$arrs1 = array应该588行左右，将下面内容注释掉或者删掉即可：

1. $arrs1 = array(0x63,0x66,0x67,0x5f,0x70,0x6f,0x77,0x65,0x72,0x62,0x79); 
2.  
3. $arrs2 = array(0x20,0x3c,0x61,0x20,0x68,0x72,0x65,0x66,0x3d,0x68,0x74,0x74,0x70,0x3a,0x2f,0x2f, 
4.  
5. 0x77,0x77,0x77,0x2e,0x64,0x65,0x64,0x65,0x63,0x6d,0x73,0x2e,0x63,0x6f,0x6d,0x20,0x74,0x61,0x72, 
6.  
7. 0x67,0x65,0x74,0x3d,0x27,0x5f,0x62,0x6c,0x61,0x6e,0x6b,0x27,0x3e,0x50,0x6f,0x77,0x65,0x72,0x20, 
8.  
9. 0x62,0x79,0x20,0x44,0x65,0x64,0x65,0x43,0x6d,0x73,0x3c,0x2f,0x61,0x3e); 

注释用法：

1. //$arrs1 = array(0x63,0x66,0x67,0x5f,0x70,0x6f,0x77,0x65,0x72,0x62,0x79); 
2.  
3. //$arrs2 = array(0x20,0x3c,0x61,0x20,0x68,0x72,0x65,0x66,0x3d,0x68,0x74,0x74,0x70,0x3a,0x2f,0x2f, 
4.  
5. //0x77,0x77,0x77,0x2e,0x64,0x65,0x64,0x65,0x63,0x6d,0x73,0x2e,0x63,0x6f,0x6d,0x20,0x74,0x61,0x72, 
6.  
7. //0x67,0x65,0x74,0x3d,0x27,0x5f,0x62,0x6c,0x61,0x6e,0x6b,0x27,0x3e,0x50,0x6f,0x77,0x65,0x72,0x20, 
8.  
9. //0x62,0x79,0x20,0x44,0x65,0x64,0x65,0x43,0x6d,0x73,0x3c,0x2f,0x61,0x3e); 

然后覆盖原来文件即可，这样dedecms程序建站调用网站版权信息的时候就不会出现powered by dedecms和链接了。
