Php 如何从数据库中获取字段值并传递给函数?
我创建了两个函数,我想从第一个函数中获取位置_4值作为$id,并将其值数组传递给第二个函数。我是如何做到这一点的?下面是我的代码:Php 如何从数据库中获取字段值并传递给函数?,php,mysql,function,mysqli,Php,Mysql,Function,Mysqli,我创建了两个函数,我想从第一个函数中获取位置_4值作为$id,并将其值数组传递给第二个函数。我是如何做到这一点的?下面是我的代码: function getbussinessdetail($profit_id) { $select="select a.account_id,a.title,a.budget,a.location_4,a.renewal_date,l.name from listing a,listinglevel l where l.value=a.level and p
function getbussinessdetail($profit_id)
{
$select="select a.account_id,a.title,a.budget,a.location_4,a.renewal_date,l.name from listing a,listinglevel l where l.value=a.level and profit_instructor_id='".$profit_id."' group by a.account_id";
$result = $GLOBALS ['mysqli']->query ($select) or die ($GLOBALS ['mysqli']->error . __LINE__);
while($rs=$result->fetch_assoc ())
{
$res[]=$rs;
}
return $res;
}
function getCityName($id)
{
if($id>0)
{
$select="select name from Location_4 where id=$id";
$result = $GLOBALS ['mysqli1']->query ($select) or die ($GLOBALS ['mysqli1']->error . __LINE__);
$rs=$result->fetch_assoc ();
return $rs['name'];
}
}
试试这个:
$profit_id = 4;
$res = array();
$res = getbussinessdetail($profit_id);
if(count($res) > 0)
{
$cityNames = array();
foreach($res as $id)
{
$cityNames[] = getCityNames($id['location_4']);
}
}
var_dump($cityNames);
或者,只需更新第一个查询并删除第二个函数:
$select="select a.account_id,a.title,a.budget,a.location_4,a.renewal_date,
l.name from listing a,listinglevel l where l.value=a.level
and profit_instructor_id='".$profit_id."' group by a.account_id";
关于这一点:
$select= "select a.account_id,a.title,a.budget,
(select name from Location_4 where id=a.location_4) as cityName,
a.renewal_date, l.name
from listing a,listinglevel l
where l.value=a.level
and profit_instructor_id='".$profit_id."' group by a.account_id";
这不是我的问题,我的问题是获取location_4字段的数组,并将其作为$id传递给函数getCityName$id您是否至少尝试了该代码…我认为这是另一个数据库中非常好的一个aproach??location_4表
