分页处理函数 showbbsProcess.php

'; //如果遍历完$arr数组里的所以元素,即$i($i从0开始)等于数组的元素个数减一,则跳出2层循环(for循环和foreach循环) if ($i==(count($arr)-1)) break 2; } } $RowCount=getRowCount($connectmysql);//一共有多少条记录 $PageCount=ceil($RowCount/$PageSize);//共有几页,ceil()函数进一取整 echo '帖子统计:'.$RowCount.'条'.' '.'共有'.$PageCount.'页 '; //当为第一页时不输出“上一页” if ($CurrentPageID != 1){ echo "上一页"; } //向前跳页 if ($CurrentPageID > 2){ echo " <<< "; } //输出详细的页数,如:【1】 for ($j=1;$j<=$PageCount;$j++){ echo "[$j]"; } //向后跳页 if ($CurrentPageID <= ($PageCount-2)){ echo " >>> "; } //当为最后一页时不输出“下一页” if ($CurrentPageID != $PageCount){ echo "下一页"; } $connectmysql->closeConn(); }

与数据库沟通的函数 showbbs_fun.php
getRowsArray($sql);
	return $arr1;
}

//该函数用来查询数据库的表的行数
function getRowCount($connectmysql){
	$sql="select * from db_content";
	$num=$connectmysql->getRowsNum($sql);
	return $num;
