帶有while循環錯誤的PHP輸出爲XML

Question

我得到錯誤：第1行第390列的錯誤：打開和結束標記不匹配：流派第0行和歌曲。

<?php 
 
header("Content-type: text/xml"); 
 
echo "<?xml version='1.0' encoding='ISO-8859-1'?>"; 
 
echo "<songs>"; 
 
$sr = $_GET["sr"]; 
 
$conn = new PDO("mysql:host=localhost;dbname=xxxxx;","xxxxx","xxxxx"); 
 
$songresults = $conn->query("SELECT * FROM `smashhits` WHERE artist LIKE'%$sr%'"); 
 
while($row=$songresults->fetch()) 
 
{ 
 
echo "<id> ID: $row[ID] </id>"; 
 
echo "<song> Song: $row[song] </song>"; 
 
echo "<artist> Artist: $row[artist] </artist>"; 
 
echo "<year> Year: $row[year] </year>"; 
 
echo "<genre> Genre: $row[genre] <genre>"; 
 
echo "<quantity> Quantity: $row[quantity] </quantity>"; 
 
} 
 
echo "</songs>" 
 
?>

我會感謝誰知道什麼是與上面的代碼會錯。

Answer 1

簡單的錯誤：

echo "<genre> Genre: $row[genre] <genre>"; 

你已經開了兩家genre標籤。我相信你不需要我告訴你它應該是

echo "<genre> Genre: $row[genre] </genre>";
