程序好像没有问题呀，在数据库里当然得建表了
新的数据库 shop 后 要怎么做？ 不太理解你这句是什么意思 ？？
mysql_connect("*", "*", "*") or
die("Could not connect: " . mysql_error());
mysql_query("SET character_set_connection='gbk', character_set_results='gbk', character_set_client=binary");
mysql_query("SET sql_mode=''");
mysql_select_db("shop");
//这个是单条数据显示的
function doSql($sql)
{
$result = mysql_query($sql);
if ($result)
{
$row = mysql_fetch_array($result);
return $row;
}
return 0;
}
//这个是多条数据的
function getRowArrayBySQL($sql)
{
$out = array();
if($sql)
{
if(function_exists('err')) {
$result = mysql_query($sql) or die("function getRowArrayBySQL() err".err($sql));
}
