DedeCMS 5.7 最近的补丁更新后，网站底部出现了织梦的版权信息“powered by dedecms”，因为这段代码不在模板里面，所以很多人不知道怎么去掉，下面就告诉你删除powered by dedecms的方法。
在include/dedesql.classs.php文件中找到第588行：
- $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);
改成：
- $arrs1 = array();
- $arrs2 = array();
这样网站底部的织梦的版权信息“powered by dedecms”就删除了。
题外话，在不影响网站的情况下，不建议去掉，毕竟程序是人家开发的，尊重下织梦版权，大家自由决定。
