php如何把图片分为一行显示3张就换行(从数据库读取)

<div class="content">
{phpx: $i=0;}
<{--loopx $data $_usershow--}>
{phpx: $username=$_usershow['username'];}
{phpx: $row = $db->fetch_first("SELECT uid FROM cdb_members WHERE username='$username'");}
{phpx: $avatar = discuz_uc_avatar($row['uid'], 'small', false);}
<div class="usershow">
<dd class="avatar">
<a href="{$_usershow['themelink']}">{$avatar}</a>
</dd>
<dt class="au"><a href="{$_usershow['themelink']}">{$_usershow[username]}</a></dt>
</div>
<{--endloop--}>
</div>
模型页的数据操作如下：
include './include/usershow.cls.php';
$_usershow = new usershow($dbop, $db); //new一个类
$data = $_usershow->select('index'); //调用类中的方法
下面住了的是和在模版页循环打印的头像相同
/*foreach ($data as $_usershow){
$username=$_usershow['username'];
$link = $_usershow['themelink'];
$row = $db->fetch_first("SELECT uid FROM cdb_members WHERE username='$username'");
var_dump($row);
$avatar = discuz_uc_avatar($row['uid'], 'small', false); //false—直接打印头像
echo discuz_uc_avatar($row['uid'], 'small', true); //true—头像链接地址
echo ($avatar);
echo('  ');
echo ($username);
echo('<br/>');
}*/

Answer 1

这个很简单，你应该是用foreach来循环的吧，那就foreach($arr as $p=>$list){
if($p%3==0){
echo $list['pic'].'<br>'; //只要是3的倍数就要在后面加一个换行就行了
}
}

<div class="content">
{phpx: $i=0;}
<{--loopx $data $_usershow--}>
{phpx: $username=$_usershow['username'];}
{phpx: $row = $db->fetch_first("SELECT uid FROM cdb_members WHERE username='$username'");}
{phpx: $avatar = discuz_uc_avatar($row['uid'], 'small', false);}
<div class="usershow">
<dd class="avatar">
<a href="{$_usershow['themelink']}">{$avatar}</a>
</dd>
<dt class="au"><a href="{$_usershow['themelink']}">{$_usershow[username]}</a></dt>
</div>
{
$i++;
if($i%3==0)
echo "<div style=\"clear:both;\"></div>";

}

<{--endloop--}>
</div>

前提<div class="usershow">这个层你要宽度高度都调好了，保证3个一行不超过上层容器的宽度并且float:left;
