复制代码 代码如下:

<?php

$dsn = "mysql:host=localhost;dbname=group";

$db = new PDO($dsn, 'root', '');

$db->exec('set names utf8');

$sql = "select conf_id from `group` group by conf_id";

//$pre = $db->prepare($sql);

//$result_arr = array();

$pre = $db->query($sql);

$result_arr = $pre->fetchAll(PDO::FETCH_ASSOC);

//print_r ($result_arr);

foreach ($result_arr as $v)

{

echo $v[conf_id]."<br>";

$vv = $v[conf_id];

$re = array();

$sql1 = "select * from `group` where conf_id = '$v[conf_id]' order by time";

$sql2 = "select * from `group` where conf_id = '$v[conf_id]' order by time DESC";

$rs1 = $db->query($sql1);

$rs2 = $db->query($sql2);

$re1[$vv] = $rs1->fetchAll(PDO::FETCH_ASSOC);

$re2[$vv] = $rs2->fetchAll(PDO::FETCH_ASSOC);

print_r($re1[$vv][0]);

print_r($re2[$vv][0]);

}
