[求助]生成静态页面问题 |
搜索了一下关于php生成静态页面问题,然后弄了个程序,但是出现了错误.
错误描述:
数据库里面有5条信息,生成的index.html,index1.html,index2.html所显示的announce_id都是1,2 不知道是什么原因.也就是所分爷的效果没出来.
程序如下:
<?
$sql_conn=@mysql_pconnect("localhost","root","root") or die ("can not connect the server");
$sql_db=@mysql_select_db("test",$sql_conn) or die ("can not connect the database");
$fp=fopen("temp.html","r");
$content = fread ($fp,filesize("temp.html"));
$onepage =2;
$sql = "select * from announce";
$query = mysql_query ($sql);
$num= mysql_num_rows ($query);
$allpages = ceil ($num / $onepage);
for ($i = 0;$i<$allpages; $i++)
{
if ($i == 0)
{
$indexpath = "index.html";
} else
{
$indexpath = "index_".$i.".html";
}
$start = $i * $onepage;
$list =" ";
$sql_for_page="select announce_id,title from announce limit $start,$onepage";
$query_for_page=mysql_query ($sql_for_page);
while ($result =mysql_fetch_array($query_for_page)){
$list.=$result[announce_id]."<br>";
}
$content = str_replace ("{mycontent}",$list,$content);
if (is_file ($indexpath)){
@unlink ($indexpath); //若文件已存在,则删除
}
$handle = fopen ($indexpath,"w"); //打开文件指针,创建文件
/*
检查文件是否被创建且可写
*/
if (!is_writable ($indexpath)){
echo "文件:".$indexpath."不可写,请检查其属性后重试!"; //修改为echo
}
if (!fwrite ($handle,$content)){ //将信息写入文件
echo "生成文件".$indexpath."失败!"; //修改为echo
}
fclose ($handle); //关闭指针
}
fclose ($fp);
die ("生成分页文件完成,如生成不完全,请检查文件权限系统后重新生成!");
