基础函数 求解释
function jieri($jieri){
$sql = select goods_id,goods_thumb,goods_name,shop_price,market_price from hc_goods where goods_id in(select goods_id from hc_goods_attr where attr_value='.$jieri.') order by goods_id desc limit 5;
global $db;  
$result = $db->getall($sql);
return $result;
}
$sql=select jieri_name from hc_shouye_jieri;
$result1 = $db->getall($sql);
echo $a=$result1[0]['jieri_name'];//可以输出
$jieri1=jieri($a);
print_r($jieri1);//这里打印不出
函数 print_r($jieri1);打印不出来啊 如果给 echo $a=$result1[0]['jieri_name']=赋值就可以打印出了
这是怎么回事啊
------解决方案--------------------
function jieri($jieri){
echo $jieri; //看看是什么?
$sql = select goods_id,goods_thumb,goods_name,shop_price,market_price from hc_goods where goods_id in(select goods_id from hc_goods_attr where attr_value='.$jieri.') order by goods_id desc limit 5;
global $db;
$result = $db->getall($sql);
print_r($result); //看看有事什么？
return $result;
}
