Question

如何访问mysql_query的特定部分？我试图用下面的代码执行此操作，但无济于事。任何帮助都将非常感激！

$rs = mysql_query("SELECT id,type FROM stuff WHERE stuffID = '$stuffID'");

   echo $rs['type']; <------ tried here

   // Add the rows to the array 
   while($obj = mysql_fetch_object($rs)) {
   $arr[] = $obj;
   }
 echo $arr['type']; <----- also tried here

在获取行之前，您无法访问该行。

while($obj = mysql_fetch_object($rs)) {
    // NOTE: $arr[] = $obj, is the same as array_push($arr, $obj),
    // I dont think you want that
    $arr = $obj; // save the row

    echo $obj->type; // you are fetching an object, not an array
}

echo $arr->type;  // you can access it here too
