php中文章标题很多的情况下怎样才能分页显示呢?
下面根据本人的体会把主要代码公开,希望对初学网友有所帮助.
＄page_size=10;(每页显示数量)
＄sql='select count(*) as rnt from mydbf';
＄sql .= ' order by mytime desc ';
＄qh=mysql_query(＄sql);
＄data=mysql_fetch_array(＄qh);
＄nr=＄data["cnt"];
＄pages=intval(＄nr/＄page_size);
if(＄nr%＄page_size) ＄pages++;
if(empty(＄page))
{
＄page=1;
＄offset=0;
}
else
{
＄offset=＄page*＄page_size-＄page_size;
}
?>
＄total = mysql_numrows(＄qh);
＄total=＄nr;
echo "";
//显示所有文章
if (!isset(＄page)){
＄page = 0;
}
//分页开始
＄start= ＄page*＄page_size;
＄offset=＄start;
＄totalpage =ceil(＄total/＄page_size);
＄pagestr ='[总数]:'.＄total;
＄pagestr.= " ".(＄page+1).'/'.＄totalpage.'页'." ";
＄xjz1= "
＄sql = 'select mytxt,content_id,clicknum,from mydbf ';
＄sql .= ' order by ltime desc limit '.＄offset.','.＄pageno;
＄res = mysql_query(＄ls_sql, ＄dbh);
＄countloop = 0;
while (＄row = mysql_fetch_array(＄res)) {
....
}
＄xjz1= "
＄xjz2=substr(＄xjz1,8);
?>
