如何去掉dedecms
解决方法很简单，如果你的网页中出现power by dedecms，或power by xxx。你就去找include/目录下的dedesql.class.php。然后打开。
然后查看代码（最好是用dreamweaver这样的编辑器，会显示页码）。
在include/dedesql.class.php文件会多出第588到第592行的那几段代码(也可以复制以下一小段代码进行搜索)，代码大致如下：
$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);
然后，就简单了，把这段代码直接删除或注释掉，保存上传覆盖，然后更新网页。
