php yii 怎么随机从数据库里获取10条数据
mysql：SELECT * FROM table order by rand() limit 10;
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",

"wrong": null,

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
}
