php中分页显示文章标题
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) $pages ;
- if(emptyempty($page))
- {
- $page=1;
- $offset=0;
- }
- else
- {
- $offset=$page*$page_size-$page_size;
- }
- ?>
- <!--
- $total = mysql_numrows($qh);
- $total=$nr;
- echo "<td colspan=3>";
-
- if (!isset($page)){
- $page = 0;
- }
-
- $start= $page*$page_size;
- $offset=$start;
- $totalpage =ceil($total/$page_size);
- $pagestr ='[<font color=green>总数</font>]:'.$total;
- $pagestr.= " ".($page 1).'/'.$totalpage.'页'." ";
- $xjz1= "<a href=$php_self?";
- $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)) {
- ....
- }
- $xjz1= "<a href=$php_self?";
- $xjz2=substr($xjz1,8);
- ?>
- <table border="0" width="100%" cellpadding="0" cellspacing="0" height="0">
- <form action="<?echo $php_self.$xjz2."&page=$page";?>" method="post">

- else

- $p=$page-1;
- echo "$xjz1&page=1>首页</a> $xjz1&page=$p>上一页</a>";
- }
- if($page>=$pages){?> 下一页 尾页 <?
- }
- else
- {
- $pp=$page 1;
- echo " $xjz1&page=$pp>下一页</a> $xjz1&page=$pages>尾页</a>";

- for ($i=1;$i<=$pages;$i ){
-
- if($i==$page)$selectxjz="selected";
