这是学生信息管理每三条一页=>

<?phpfunction news($pageNum = 1, $pageSize = 3){$array = array();$mysql=new mysql();$rs = "select * from user  limit " . (($pageNum - 1) * $pageSize) . "," . $pageSize;$r = $mysql->query($rs);while ($obj = mysqli_fetch_object($r)) {$array[] = $obj;}return $array;}function allNews(){$mysql=new mysql();$rs = "select count(*) num from user"; $r = $mysql->query($rs);$obj = mysqli_fetch_object($r);return $obj->num;}@$allNum = allNews();@$pageSize = 3; @$pageNum = empty($_GET["pageNum"])?1:$_GET["pageNum"];@$endPage = ceil($allNum/$pageSize); @$array = news($pageNum,$pageSize);?><form><table border="1"  cellspacing="0" align="center" style="z-index:10;"><tr><td>ID</td><td>username</td><td>mela</td><td>academic</td><td>profession</td><td>number</td><td>email</td><td>qq</td><td>pubtime</td><td>status</td><td>modify</td><td>delete</td></tr><?php foreach($array as $k=>$v){ ?>       <tr><?phpecho "<td>{$v->id}</td>";echo "<td>{$v->username}</td>";echo "<td>{$v->mela}</td>";echo "<td>{$v->academic}</td>";echo "<td>{$v->profession}</td>";echo "<td>{$v->number}</td>";echo "<td>{$v->email}</td>";echo "<td>{$v->qq}</td>";echo "<td>{$v->pubtime}</td>";echo "<td>{$v->status}</td>";?></tr></form><?php } ?></table><div><a href="?pageNum=1">首页</a><a href="?pageNum=<?php echo $pageNum==1?1:($pageNum-1)?>">上一页</a><a href="?pageNum=<?php echo $pageNum==$endPage?$endPage:($pageNum+1)?>">下一页</a><a href="?pageNum=<?php echo $endPage?>">尾页</a></div>

 结果为：

php在函数前加@的作用：

@是错误控制运算符，用屏蔽错误提示
比如：
@mysql_connect（） 不会出现Warning。
