再问一个数组的问题

[weki]

<?
$tempid="20";
$arr=array(12,15,26,58,89);
if(in_array($tempid,$arr))
{
echo('I am here');
}
?>
这样是正确的。但是
$arr=array(12,15,26,58,89);
//这里改成
$arr=array($row->idlist);//语法是正确的，$row->idlist的值就是：12,15,26,58,89
但是$arr=array($row->idlist);就是运行不了，知不知为什么呀？

[weki]

是呀。字符串：12,15,26,58,89,

[bluemeteor]

那这样
$arr=array();
$arr=explode(",",$row->idlist)

[bluemeteor]

那这样
$arr=array();
$arr=explode(",",$row->idlist)

[xuzuning]

$arr = explode(",",$row->idlist);
$arr = split(",",$row->idlist)
eval("\$arr=array({$row->idlist});");
$arr = eval("return array({$row->idlist});");

任选其一

[weki]

xuzuning(唠叨):

能不能具体点，
$arr = explode(",",$row->idlist);
$arr = split(",",$row->idlist)
eval("\$arr=array({$row->idlist});");
$arr = eval("return array({$row->idlist});");

//这里是两个方法么？？能不能具体点是什么两个方法呀。55~先谢了

[weki]

xuzuning(唠叨):


太感谢了。5555!!!!!!!!!!1成功了

[myblessu]

应该是赋值方式不对

[xuzuning]

$arr = $row->idlist;

[xuzuning]

$arr = $row->idlist;

[bluemeteor]

$arr=array();
$arr=$row->idlist

[多菜鸟]

up

[weki]

都是不行呀。请问其它方法。55~````````````

[weki]

$row->idlist是text类型，会不会是数据类型不对，请问要改成什么类型呀？？

[myblessu]

$row->idlist 得到是一个字符串吧,那很定是不对了.
