从数据库随机取出来之后再用php处理一下，按照你的需求再排序咯。然后楼主还有什么疑问的话，还不懂，可以去后盾人看看，里面有些资料，兴许能够帮助你

php mysql 只取10个数据

$sql = "SELECT * FROM chat WHERE id ".$lastID." ORDER BY id ASC LIMIT 60";

改为

$sql = "SELECT * FROM chat WHERE id ".$lastID." ORDER BY id ASC LIMIT 0，10";

php 循环二维数组取十条数据

你给出的数据组织形式，貌似是json，那么你可以直接用json_encode() 和 json_decode()进行转换后，再进行处理。

示例代码：

?php

$json = '{

"6846": {

"userid": "6846",

"expertname": "三剑客",

"firstrate": "0",

"wrong": null,

"firstqs": "2011254",

"lastrate": "0",

"lastnum": "0",

"kjtime": "2012-09-30 00:00:00",

"successrate": "0",

"curqs": " (2012267,2012266,2012262,2012259,2011256,2011255,2011254 )",

"lastpaiming": "1",

"curpaiming": "1"

},

"9205": {

PHP中如何取数据库某一字段的某一状态在的后10条数据

先找出状态＝1的最大cid:X，然后搜索cid = X的那一行：

select name from 表名 where cid = (select max(cid) from 表名 where status=1) 其中status类型要为int

如果是varchar，就要写成status='1'

php怎么把从数据库里查询的数据十条一页的显示出来

按照楼主已死贴出完整代码，看不懂再问

$sql="select * from `user` order by `id` desc";//自己随便写一个sql语句测试用，根据自己需求替换，不要加limit

$pagesize=10;

$num=mysql_num_rows(mysql_query($sql));

$pagecount=ceil($num/$pagesize);

$pageall=$num;

if(!isset($_GET["page"])){//这里翻页模式用GET方式传参解决，?page=1的方式

$pageindex="1";

}else{

$pageindex=$_GET["page"];

if($pageindex==""){

$pageindex="1";

}elseif(!is_numeric($pageindex)){

$pageindex="1";

}elseif(substr_count($pageindex,".")!=0){

$pageindex="1";

}elseif($pageindex$pagecount){

$pageindex=$pagecount;

}elseif($pageindex=1){

$pageindex="1";

}

}

if($pageindex$pagecount){

$start=($pageindex-1)*$pagesize;

$sql1=$sql." limit ".$start.",".$pagesize;

}else{

if($num%$pagesize!=0){

$start=($pageindex-1)*$pagesize;

$sql1=$sql." limit ".$start.",".($num%$pagesize);

}else{

$start=($pageindex-1)*$pagesize;

$sql1=$sql." limit ".$start.",".$pagesize;

}

}

$result=mysql_query($sql1);

while($RS = @mysql_fetch_array($result)){

//按要求读出每次循环的字段

}

php如何重复调用输出数据？比如说10条。

明白你的意思了。

$a = mysql_query("select * from table_name", $link); //这个地方你的写法有问题，两个参数外不需要加引号，我的是正确的

这个$a只是mysql一个资源集，你要用mysql_fetch_array这个函数循环从里面提取数据，具体可以查手册mysql_fetch_array的用法，完整代码是：

$a = mysql_query("select * from table_name", $link);

while ( $row = mysql_fetch_array($a) )

{

print_r($row); //$row 就是一行数据，是一个数组

}
