如何刪除「警告：無法使用標量值作爲數組」

Question

這裏是我的代碼：

$i = 0; 
$list4 = array(); 
while($row_sent = $GLOBALS['db']->sql_fetchrow($res_sent)) 
{ 
    $sql_sent2 = "SELECT * FROM ".$GLOBALS['table']['sent']." WHERE `sent_id` ='".$row_sent['sent_id']."'"; 
    //echo $sql_size2; exit; 
    $res_sent2 = $GLOBALS['db']->sql_query($sql_sent2); 
    $num = $GLOBALS['db']->sql_numrows($res_sent2); 
    if($num > 0) 
    { 
     while($row_sent2 = $GLOBALS['db']->sql_fetchrow($res_sent2)) 
     { 
      $list4[$i]['sent_id']    = $row_sent2['sent_id']; //this line shows error 
      $list4[$i]['sent_name']   = $row_sent2['sent_name'];//this line shows error 
      $list4[$i]['sent_qty']   = $row_sent['sent_qty'];//this line shows error 
     } 
    } 
    else 
    { 
     $list4=0; 
    } 
    $i++; 
} 

Answer 1

嘗試。

聲明$list4作爲循環開始之前的數組。

$list4[] = array(); 

這可能是有用的。

謝謝。
