Pagination means dividing a page into two or more pages.
There is an automatic paging mechanism that can divide the content in the mobile Web form
into a group of smaller pages for presentation, suitable for specific equipment. This mechanism also renders user interface elements that can be used to navigate to other pages.
The following is a PHP paging code, which is relatively simple.
<?php function genpage(&$sql,$page_size=10) { global $pages,$sums,$eachpage,$page; //总页数,总记录,每页数,当前页 $page = $_GET["page"]; if($page ==0)$page =1; $eachpage = $page_size; $pagesql = strstr($sql," from "); $pagesql = "select count(*) as ids ".$pagesql; $conn = mysql_query($pagesql) or die(mysql_error()); if($rs = mysql_fetch_array($conn))$sums = $rs[0]; $pages=ceil($sums/$eachpage); if($pages==0)$pages=1; $startpos = ($page-1)*$eachpage; $sql .=" limit $startpos,$eachpage "; } //显示分页 function showpage() { global $pages,$sums,$eachpage,$page; //总页数,总记录,每页数,当前页,其它参数 $link=$_SERVER['PHP_SELF']; echo "记录".$sums.":".$eachpage." "; echo "页数".$page."/".$pages." "; $p_head=$page-5; if($p_head<=0)$p_head=1; //页码循环开始数 前5个 $p_end=$page+5; if($p_end>$pages)$p_end=$pages; //页码循环结束数 后5个 echo "[<a href=$link?page=1>首页</a>] "; for($i=$p_head;$i<=$p_end;$i++) { if($i!=$page) echo "<a href=$link?page=$i>[$i]</a> "; else echo "<b><strike>[$i]</strike></b> "; } echo " [<a href=$link?page=$pages>末页</a>]"; } ?>
