桌面中心(四) 数据显示
最后一步就是显示了。
下面这个程序要通过参数来调用。
比如php.php?jpg=jpg
后面的jpg是表格名。记住一定要的呀,不然就不能运行了,会显示程序出错。
大家可以把下面这个程序改一下。这样就可以更加美观了。
以下是源程序:
<html>
<head><title>显示</title>
</head>
<body>

$result=mysql_db_query("elong",$query); //执行查询
$num=mysql_numrows($result);
$page=round($page);
$pagesize=4;
if ($page==0){
$page=1;}
else{
