由于某种原因，除非我忽略了一些东西，这段代码在这里：
<?
include_once("connect.php");
$sql = "SELECT * FROM categories ORDER BY category_title ASC";
$res = mysqli_query($con,$sql) or die(mysql_error());
$categories ="";
if (mysqli_num_rows($res) > 0) {
while($row = mysqli_fetch_assoc($res)){
$id = $row['id'];
$title = $row['category_title'];
$description = $row['category_decription'];
$categories .= "<a href='#' class='cat_links'>".$title." - <font size='-1'>".$description."</font></a>";
}
echo $categories;
} else {
echo"<p>There are no categories available yet.</p>";
}
?>
似乎将此反映在页面上：
0）{while（$ row = mysqli_fetch_assoc（$ res））{$ id = $ row [＆＃39; id＆＃39;]; $ title = $ row [＆＃39; category_title＆＃39;]; $ description = $ row [＆＃39; category_decription＆＃39;]; $ categories。=＆＃34;＆＃34;。$ title。＆＃34; - ＆＃34;。$ description。＆＃34;＆＃34 ;; } echo $ categories; } else {echo＆＃34; 目前还没有类别。
＆＃34 ;; }？＆gt;
我做错了什么？
提前致谢！
