phpcms使用添加php原生支持的实现方法

{php $my_arr=array('1'=>'aaa','3'=>'bbbb','4'=>'cccc','15'=>'dddd', } 

{$my_arr[$r[catid]]}

<?php
$uid=param::get_cookie('_userid');
if(is_array($_GET)&&count($_GET)>0)//先判断是否通过get传值了
{
if(isset($_GET["catid"]))//是否存在"caatid"的参数
{
if($_GET["catid"]==19){$sql="select * from ec_changdix_data as b where a.id=b.id and userid=$uid and status=99 and catid in (20,21,22)";}
if($_GET["catid"]==23){$sql="select * from ec_changdix as a , ec_changdix_data as b where a.id=b.id and userid=$uid and status=99 and catid=23";}
}else{$sql="select * from ec_changdix as a , ec_changdix_data as b where a.id=b.id and userid=$uid and status=99 and catid in (20,21,22,23)";}
}
?>
{ec:get sql="$sql" num="100"}
{loop $data $info}

<div id="dwdw"></div>
<script>
$(document).ready(function(){
