XML php变量元素编号

Question

 $aid= $_GET["aid"];
 echo $xml->orders->ITEM["$aid"]->name;

With this script I'm trying to display the value of an XML page. The variable $aid is the number of elements. This can be 0 to 1000.

Only nothing displays when I run this script.

This works fine

 $aid= $_GET["aid"];
 echo $xml->orders->ITEM[1]->name;

Answer 1

You're assigning the key wrong, use just the variable name without the apostrophes.

echo $xml->orders->ITEM[$aid]->name;
