dedecms官方5.7版本升級后，版權(quán)標(biāo)簽{dede:global name='cfg_powerby'/}調(diào)用出來后會出現(xiàn)：“powered by dedecms”，格展建議您不要去掉，畢竟用了開源程序，最好尊重下版權(quán)，織夢開源程序也不容易，希望大家也支持下。
現(xiàn)在告訴大家怎么去除織夢底部的 powered by dedecms版權(quán)信息：
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：
$arrs1 = array();
$arrs2 = array();
