織夢dedecms調用網站版權信息是會出現powered by dedecms鏈接到www.dedecms.com這個網址，站在優化角度上來說，這種單向鏈出鏈接對我們來說多少有些不利，這里也是用織夢建站我們手動修改的一個地方，下面說說教程：

去掉powered by dedecms網站版權信息教程：

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

Ctrl+f查找$arrs1 = array應該588行左右，將下面內容注釋掉或者刪掉即可：

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); 

注釋用法：

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); 

然后覆蓋原來文件即可，這樣dedecms程序建站調用網站版權信息的時候就不會出現powered by dedecms和鏈接了。
