phpwhere多条件查询

⑴ 关于php多条件模糊查询后分页问题！

//以上信息为公告和右侧的两个新闻

if (isset($_GET['sousuo'])) $searchname = $_GET['sousuo'];//得到搜索关键词
else if (isset($_POST['sousuo'])) $searchname = $_POST['sousuo'];

if(!isset($searchname))
{
echo "<script>location.href='index.php';</script>";

$jianqitian=date('Y-m-d',strtotime("$a-7 day"));//减去7天时间

switch($typename)
{
case "职位名":
if($shijian=="")
{
$tiaojian="Shenhe=1 and Gzxx like '%".$searchname."%' order by Adddate desc";

}

}

$perNumber=5; //每页显示的记录数
$page=$_GET['page']; //获得当前的页面值
$count=mysql_query("select count(*) from ejz_wor where ".$tiaojian.""); //获得记录总数

$rs=mysql_fetch_array($count);
$totalNumber=$rs[0];
$totalPage=ceil($totalNumber/$perNumber); //计算出总页数
if (!isset($page)) {
$page=1;
} //如果没有值,则赋值1
$startCount=($page-1)*$perNumber; //分页开始,根据此方法计算出开始的记录

<?
}
if ($page != 1) { //页数不等于1
?>

<?php echo "总共".$totalPage."页，";?>
<a href="wj.php?page=<?php echo $page - 1;?>&sousuo=<?php echo $searchname;?>">上一页</a> <!--显示上一页-->
<?php
}
for ($i=1;$i<=$totalPage;$i++) { //循环显示出页面
?>
<a href="wj.php?page=<?php echo $i;?>&sousuo=<?php echo $searchname;?>"><?php echo $i ;?></a>
<?php
}
if ($page<$totalPage) { //如果page小于总页数,显示下一页链接
?>
<a href="wj.php?page=<?php echo $page + 1;?>&sousuo=<?php echo $searchname;?>">下一页</a>
<?php
}
?>

⑵ php 多条件查询数据库MySQL

SELECT * FROM `表名` WHERE bookid=22
获取BOOKID为22的记录，输出$uid=
if(strpos($uid,"2")!==false):echo"包含";else:echo"不包含";endif;
判断UID中是否含有2
MYSQLI方法统计数量

$num=mysqli_num_rows(mysqli_query($mysqli,"SELECT id FROM `表名` where pinglun=1"));
统计该表中pinglun=1的记录数量

⑶ thinkphp where有多个条件进行复合查询，关系为or，代码如下

请参考thinkphp开发手册的查询语言一节，可以有不同写法，我这里写一种供你参考：

$where1=array(
'Key'=>array('like','zt'.'%'),
'code'=>'02'
);
$where=array(
'modes'=>1,
'Key'=>array('like','tm'.'%'),
'code'=>'02',
'_complex'=>$where1,//复合查询
'_logic'=>'or'//关系为or
);
//查询语句
$mysql=M('Mysql')->where($where)->select();
