但是這次的DEDECMS V5.7版本更新后，在前臺網頁底部會出現織夢版權信息 “powered by dedecms”，很多人都不知道怎么去掉的（不建議你去掉，畢竟程序是人家開發的，你免費用了），因為這段代碼并不存在于HTM模板中。

現在告訴大家怎么去除織夢底部的 powered by dedecms版權信息：

在include/dedesql.class.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：

$arrs2 = array();  

保存文件并上傳即可。大家如果覺得實在影響美觀或者怕導出權重，建議去掉后在網頁首頁友情留個官方鏈接或者底部信息留個powered by dedecms 不帶鏈接即可，請大家尊重版權哈！
